How Thermography Surveys Prevent Electrical Fires in Chemical WarehousesA thermography survey helps identify hidden overheating in electrical systems before visible damage appears. Chemical warehouses carry a higher fire risk because flammable liquids, vapours, packaging materials, and electrical systems often operate within the same facility. In this environment, a small hidden fault can become serious if it is not found early. A loose connection, overloaded breaker, overheating cable, or ageing electrical component may continue working without any visible warning. The panel may look normal, while heat is already building inside. A thermography survey helps detect abnormal heat before visible damage appears. For businesses looking for infrared thermography inspection in Sri Lanka, it is a practical way to identify electrical fire risks, plan repairs, and protect people, stock, and operations before a fault escalates. What is a Thermography Survey? A thermography survey is a non-contact inspection carried out using an infrared thermal imaging camera. The camera detects heat patterns in electrical and mechanical equipment while the system is operating. A trained thermographer then reviews the images to identify abnormal temperature differences. These temperature differences may indicate: Loose electrical connections Overloaded circuits Unbalanced electrical loads Damaged or ageing components Poor ventilation inside panels Developing electrical faults Thermography is most useful when equipment is live and operating under normal or meaningful load. This is important because some electrical faults only appear when current is flowing through the system. A panel may look safe when switched off, but show clear overheating during normal operation. Why Chemical Warehouses Have Higher Electrical Fire Risk Every fire needs heat, fuel, and oxygen. In a chemical warehouse, fuel may already be present through stored chemicals, vapours, cardboard packaging, plastic containers, wooden pallets, drums, and other combustible materials. That makes heat control especially important. Electrical systems can become ignition sources when they are not properly inspected or maintained. Common risks include: Loose or corroded cable connections Overloaded distribution boards Faulty breakers, contactors, or isolators Damaged cable insulation Poor cable terminations Overheating motors or pumps Lighting circuits exposed to dust, heat, or moisture Electrical panels placed close to storage areas In a general commercial building, these issues may lead to breakdowns or repair costs. In a chemical warehouse, they can create wider risks for people, property, inventory, and business continuity. How Thermography Surveys Detect Electrical Fire Risks Thermography does not prevent fire by itself. Its value is in early detection. It gives maintenance and safety teams clear evidence of where heat is building, so they can act before the fault becomes dangerous. Electrical Hot Spots Loose electrical connections are one of the most common causes of overheating. When a connection becomes loose, resistance increases. Higher resistance creates heat. As the connection heats up, it can weaken further and create even more heat. If ignored, this can lead to: Melted insulation Burnt terminals Electrical arcing Panel damage Fire ignition A thermal image can reveal the hot spot before there is visible damage. The maintenance team can then inspect, isolate, and repair the issue before it becomes severe. Overloaded Circuits Chemical warehouses often change over time. New lighting, pumps, ventilation systems, sensors, battery chargers, office areas, or storage zones may be added to the existing electrical network. If the system is not reviewed properly, some circuits may carry more load than they were designed for. A thermography survey can show where breakers, cables, or panels are running hotter than expected. Engineers can then check whether the issue is caused by overload, poor distribution, incorrect equipment selection, or another fault. This helps prevent electrical stress from turning into equipment failure or fire risk. Load Imbalance Many industrial warehouses use three-phase electrical systems. The load should be distributed evenly across the phases. If one phase carries more current than the others, cables, breakers, transformers, and connected equipment can overheat. It can also reduce efficiency and shorten equipment life. Thermography can show uneven heat patterns that may indicate load imbalance. This is useful in warehouses where equipment is frequently added, moved, or modified. Why Visual Electrical Inspections Are Not Enough A panel may look normal in visible light, while thermal imaging shows developing heat-related faults. Visual inspections are still important. They can identify exposed cables, broken covers, corrosion, blocked panel access, poor housekeeping, and unsafe storage near electrical equipment. However, visual checks cannot detect hidden heat. A cable termination may look fine on the outside but still be loose. A breaker may appear normal but run hot internally and a panel may show no visible damage while one section is already overheating. Thermography adds another layer to the inspection process by showing what the naked eye cannot see. Key Areas to Inspect in a Chemical Warehouse A good thermography survey should be planned around the warehouse layout, electrical distribution system, load conditions, and fire risk areas. It should not be limited to a quick scan of the main electrical panel. Key areas to inspect include: Main and sub-distribution boards Motor control centres Transformers Breakers and isolators Cable termination points Contactors and fuse holders Pumps and motors Ventilation and exhaust systems Lighting circuits Battery charging areas Electrical panels near chemical storage zones For chemical warehouses, the inspection plan should also consider site permits, PPE, ventilation, access restrictions, hazardous storage areas, and safe working procedures. The survey should be carried out under realistic load conditions. If it is done during low-load periods, some faults may not show clearly. What a Good Thermography Report Should Include A good thermography report should explain the issue clearly, not only show thermal images. It should include: Thermal images and normal reference images Exact location of each issue Description of the fault Risk level or severity Likely cause Recommended corrective action Repair priority For chemical warehouses, the report should be clear enough for engineers, safety officers, warehouse managers, and decision-makers to understand the risk and next step. Thermography as Part of Electrical Fire Prevention Thermography is valuable, but remember, it should not be your only safety measure. Companies that invest in regular

What Is Protection Relay Testing and Why Is It Critical for Electrical Safety?   When a fault occurs on an electrical network, every millisecond matters. A protection relay that fails to operate correctly can lead to transformer and cable damage, switchgear failure, extended outages, lost production, and serious safety incidents. Protection relay testing is what confirms — before a real fault does — that the protection relay will detect that fault and trip the right breaker at the right time. For any facility that depends on reliable power — a factory, a hotel, a hospital, a solar plant or a substation — testing verifies that the protection system will respond correctly at the one moment it truly matters. Key takeaways Protection relay testing confirms a protection relay will detect a fault and trip correctly — instead of finding out it won’t during an actual fault. Testing alone is not enough. A protection relay can pass every test and still be set wrong for the network it protects. A protection coordination study defines the correct settings; testing verifies them. For solar and grid-connected plants, relay testing is also a grid-connection requirement (for example, CEB acceptance in Sri Lanka). Test reports should be reviewed and signed by a chartered electrical engineer — the deliverable that satisfies compliance, insurance and utility sign-off. What Is a Protection Relay? A protection relay is a device that monitors electrical parameters and identifies abnormal operating conditions. When a fault is detected, the protection relay sends a trip command to a circuit breaker or other protective device to isolate the affected section of the network. The objective is straightforward: to protect people, equipment, and electrical infrastructure from damage. Protection relays are commonly installed in: Industrial facilities and manufacturing plants Electrical substations Commercial buildings Power plants and renewable energy projects Data centres Water and wastewater treatment facilities Without protection relays — and without confidence that they are set and working correctly — a fault can spread through a network and destroy expensive equipment in moments. Why Protection Relay Testing Is Important for Electrical Safety Protection systems are installed on the expectation that they will perform correctly. But settings drift, components age, firmware changes, and installation errors can sit undetected for years. Testing confirms that a protection relay still operates according to the original protection philosophy. Professional protection relay testing services verify settings, trip functions, communication schemes, and overall protection performance under simulated fault conditions. This delivers four practical benefits. Prevent Equipment Damage Faults place severe stress on transformers, motors, cables, generators and switchgear. A protection relay that trips too late can let a contained fault escalate into a major failure. Routine testing — combined, for transformers, with regular transformer testing — gives a clearer picture of equipment condition and risk. Improve Personnel Safety Electrical faults can create dangerous conditions, including arc flash. Fast, accurate fault clearing reduces exposure to these hazards. Pairing relay testing with an electrical safety audit assesses hazards, compliance gaps and protection performance together. Reduce Unplanned Downtime Unexpected electrical failures interrupt production, delay operations and drive up maintenance cost. Testing surfaces weaknesses in the protection system before they cause an outage. Support Compliance and Insurance Requirements Many facilities keep documented test records as part of compliance and risk-management programmes. Test reports provide evidence that protection systems are maintained to recognised engineering practice — and are often required by insurers and utilities. What Happens When a Protection Relay Fails? Protection relay failures are rarely obvious. A protection relay can look perfectly operational while a critical setting has been changed or an internal issue has developed. When this happens, the consequences can include: Transformer and motor damage Switchgear faults Arc flash incidents Extended power interruptions Production shutdowns In the worst case, a fault that should have been isolated within milliseconds spreads across a much larger section of the network. This is exactly why relay testing should be treated as a preventive measure — not a reaction to failure. Types of Protection Relays and Their Testing Requirements Different protection functions call for different test procedures. The table below summarises the most common protection relay types and what testing confirms for each. Protection relay type ANSI code What testing verifies Overcurrent 50 / 51 Pickup current, time-current curve, instantaneous trip, grading with upstream/downstream devices Earth fault 50N / 51N Sensitivity, pickup threshold, trip timing Differential 87 Operating pickup, bias/restraint slope, in-zone fault tripping, through-fault stability Voltage / frequency 27/59, 81 Correct operation when voltage or frequency moves outside set limits Grid-interface (solar/DG) U/O V, U/O F, ROCOF, vector shift Anti-islanding and grid-protection response required for utility grid connection Distance 21 Zone reach and fault-response accuracy (mainly transmission/utility networks) Overcurrent (50/51) and differential (87) protection are the workhorses across industrial, commercial, hospitality and renewable sites, so they receive the most attention in practice. Distance protection (21) is included for completeness but is mainly a transmission- and utility-network function. For solar PV and generator-connected sites, the grid-interface functions deserve particular care: under/over voltage, under/over frequency, ROCOF and vector-shift protection govern how the plant connects to — and disconnects from — the grid during a disturbance. These are not optional extras; they are the functions the utility checks before approving grid connection. Vibhawa handles this end to end for renewable-energy plants: the protection system study, relay configuration, and testing, through to the witness verification performed in front of utility engineers to secure the grid connection. We have delivered this for numerous MW-scale solar PV plants connecting to the grid. Grid-connection protection — MW-scale solar track record Vibhawa has carried out protection system studies, relay configuration, testing and utility witness verification for grid-connected solar PV plants including the 3 MW Cheval Blanc open-sea floating plant (Maldives), the 1.6 MW Pyramid Lanka solar project, a 1.16 MW solar PV plant for Jay Jay Mills, and rooftop solar grid-connection support for Warwick Solar Power — alongside protection-coordination work for grid-connected power plants such as the 10 MW Ace Power waste-to-energy facility, Sri Lanka’s first. What

Vibhawa Completes Electrical Audit and Arc Flash Study for Fonterra Sri Lanka Manufacturing Plant An arc flash study is one of the most consequential pieces of work a manufacturing plant can commission, because the findings affect personnel safety, protective device settings, and how the maintenance team is allowed to work near energised equipment. Electrical issues in a plant rarely show up as a single visible fault — they begin as heat, poor selectivity, ageing connections, incorrect protection settings, or work practices that no longer match the way the plant operates. That is why a proper electrical safety audit must go beyond a visual checklist. We, at Vibhawa Consultants, recently completed the annual electrical audit and thermography survey of the Fonterra Sri Lanka manufacturing plant for the fifth consecutive time. This year’s work also included a protection coordination study and arc flash study for the complete electricity distribution system, covering the 33kV system and low voltage network. The project concluded with an arc flash safety awareness session for Fonterra’s maintenance team, followed by a Q&A discussion. Here’s everything you need to know about this: Project Scope This assignment brought together three connected areas of engineering work: Annual electrical audit of the manufacturing plant Infrared thermography survey of live electrical assets Protection coordination and arc flash analysis across the full distribution system For a facility that depends on continuous production, each part serves a different purpose. The audit checks the wider condition, safety and compliance position of the installation. The infrared thermography inspection helps identify abnormal heating while equipment is in service. The protection coordination and arc flash study reviews how the network behaves during fault conditions and what exposure may exist for personnel working near energised equipment. Together, these activities give the maintenance and engineering teams a clearer basis for decisions. Why Electrical Safety Audits Matter in Manufacturing Facilities Manufacturing plants like Fonterra carry a different level of electrical dependency from many commercial sites. Production equipment, utilities, refrigeration, packaging, process control and maintenance access all depend on stable power. A fault in one section can affect more than one machine. So, if protection settings are not selective, a local issue can lead to a wider interruption. A structured electrical safety audit helps plant teams understand: Where immediate electrical hazards may exist Whether maintenance priorities are correctly ranked Which defects require shutdown planning How safety and production continuity are connected Whether past corrective actions have held over time For Fonterra, the fifth consecutive annual assessment also added continuity. Repeated checks help compare the current condition against previous observations. This is important because risk changes as load, asset condition and operating demands change. What an Infrared Thermography Survey Reveals in a Live Plant The thermography survey was a key part of the project as it allowed us to inspect live equipment without interrupting plant operation. Thermal imaging is useful for identifying early warning signs such as: Loose cable terminations Overheated joints Phase imbalance Excessive loading Poor contact resistance Deteriorating components inside panels These findings are valuable only when they are interpreted correctly. A thermal anomaly on non-critical equipment does not carry the same operational consequence as a similar reading on a main distribution panel. Vibhawa’s assessment considered the asset, load condition and location of each finding. This helped Fonterra’s maintenance team prioritise action based on practical risk rather than temperature readings alone. This is where condition monitoring becomes more than inspection. It becomes a planning tool to reduce unplanned failures. How a Protection Coordination Study Improves Plant Reliability The protection coordination study reviewed how protective devices should operate during a fault. The objective is simple: the device closest to the fault should isolate the affected section where possible, while upstream supply remains available. When this does not happen, one fault can shut down a larger part of the plant. That’s why we studied the full distribution arrangement, including the 33kV system and the low voltage network, since coordination cannot be judged by one voltage level alone. A protection study typically considers: Fault levels Protective device settings Time-current behaviour Selectivity between upstream and downstream devices Equipment ratings System response during abnormal conditions Better coordination can reduce the scale of interruption, support safer fault isolation and help maintenance teams understand how the network is expected to respond. This also connects naturally with protection system testing, where protection relays, circuit breakers, CTs, VTs and related circuits are checked against intended performance. What an Arc Flash Study Tells You About Worker Exposure The arc flash study added another safety layer to the project. Arc flash analysis evaluates the potential incident energy released during an arcing fault and helps determine the level of hazard faced by personnel working near energised equipment. This is not only a compliance exercise. It affects daily work decisions.The study helped us identify where higher exposure may exist across the distribution system. It also supports decisions around: Safe working boundaries Personal protective equipment Equipment labelling Switching practices Isolation procedures Work authorisation and supervision This is critical because Fonterra’s system includes both 33kV and low voltage assets. Work at these levels requires a clear understanding of the hazard, not general assumptions. Awareness Session on Arc Flash Safety After the studies were completed, our engineering experts at Vibhawa lead by Sandika Sawandi – Power System Design & Simulation Engineer of Vibhawa conducted an arc flash safety awareness session for Fonterra’s maintenance team. This step matters because technical reports are only useful when the people responsible for operation understand how to apply the findings. The session covered why protection coordination matters, and how maintenance decisions should account for exposure. The Q&A allowed the team to raise questions about plant access, equipment and work routines. This made the project more useful at site level. It connected engineering analysis with the decisions maintenance staff make during inspections, switching and fault response. How Vibhawa Combines Field Testing, System Studies, and Safety Training This project reflects Vibhawa’s strength in field testing, system studies and practical guidance.

From Intern to Industry Pioneer: A Proud Milestone for Vibhawa and Women in Engineering We are delighted to share that Malki Madapatha, Assistant Manager – Testing & QA, has officially been certified as a Level 2 Infrared Thermographer. This makes her Sri Lanka’s first female Level 2 thermographer — a personal milestone for Malki, and a significant one for the industry as a whole. A Milestone for Sri Lankan Engineering Malki’s journey reflects what we stand for at Vibhawa. She started her career with us as an intern and grew through dedication, curiosity, and hands-on field experience into a specialist in one of the most technical and niche disciplines in electrical engineering. Today she stands among a rare group of professionals globally with advanced thermography credentials, and as one of the first women in Sri Lanka to reach this level, she represents a powerful step forward for women in engineering and STEM. What Level 2 Thermographer Certification Means Level 2 is not an entry-level qualification. Malki’s certification is issued by IRISS, a globally recognised training authority whose Level 2 (CAT 2) programme is designed to meet and exceed ISO 18436 Part 7 and ANSI/ASNT CP-105 and CP-189 recommended practices — the international standards that govern condition monitoring and non-destructive testing personnel. Reaching Level 2 is demanding by design. Candidates must already hold a current Level 1 certification and demonstrate at least 420 hours of documented field experience in infrared thermography before they are eligible to take the course. The Level 2 programme itself covers advanced infrared theory, equipment calibration, error source identification, quantitative report generation, and the assignment of repair priorities based on thermal severity. Certification is granted only after successful completion of the course, a written exam, and a field assignment. In practice, a Level 2 thermographer in Sri Lanka — or anywhere — is qualified to lead inspections independently, interpret quantitative thermal data rather than just spot patterns, provide technical direction to Level 1 personnel, and generate the kind of engineering reports that insurance companies, plant owners, and certifying authorities can act on. Why This Matters for Industrial and Commercial Facilities Infrared thermography is a non-contact, non-destructive technique for identifying hidden electrical faults — loose connections, overloaded conductors, failing breakers, deteriorating insulation — before they cause downtime, fires, or equipment loss. For data centres, hospitals, hotels, manufacturing plants, and critical infrastructure, a routine thermal inspection programme is one of the highest-return preventive maintenance investments available. The quality of a thermography survey, however, depends almost entirely on the thermographer behind the camera. A Level 1 operator can flag anomalies. A Level 2 thermographer can quantify them, prioritise them, and produce reports that engineering teams and insurers will rely on. That is the difference Malki’s certification makes for our clients. Vibhawa’s Thermography Capability With this certification, Vibhawa continues to be the only company in Sri Lanka with both Level 3 and Level 2 certified thermographers in-house. Our thermography team operates under ISO 9001:2015 quality management (SGS/UKAS certified) and delivers infrared thermography services across Sri Lanka and the Maldives, supporting our broader electrical testing and commissioning capability. Where Our Thermographers Have Worked Malki and our wider thermography team have delivered surveys not only across Sri Lankan industrial and commercial sites but also on international projects, including resort properties in the Maldives such as Cheval Blanc Randheli. This combination of local depth and overseas project exposure is what allows us to serve clients with high-stakes assets and tight reliability requirements. Inspiring the Next Generation More than anything, we hope Malki’s achievement encourages more young women in Sri Lanka to step into engineering and pursue specialised technical careers with confidence. At Vibhawa we don’t just practice thermography — we are committed to sharing knowledge, building expertise, and shaping the future of the industry through upcoming training and learning initiatives. If you would like to discuss a thermography survey for your facility, or learn more about our testing capability, please get in touch with our team.

Ensuring Energy Meter Accuracy: Why Field Calibration Matters More Than Ever While everyone has turned energy-conscious today, accuracy isn’t just a technical term. It has now become a business essential. Whether you manage a factory, commercial building, or a power distribution network, your energy meter is the foundation of every decision about cost, efficiency, and performance. Even a small inaccuracy can quietly drain money, distort energy reports, and affect sustainability goals. That’s why regular energy meter calibration is so important; it keeps your measurements reliable, your energy management strategies effective, and your operations fully compliant with global standards like IEC and ISO 50001. At Vibhawa Consultants, we now offer field energy meter calibration services in Sri Lanka, helping businesses verify their energy meters on-site, accurately and efficiently, without downtime. Want to know how? Keep reading. Why Does Energy Meter Accuracy Matter? Your energy meter is like the heartbeat of your facility. It tracks how much power/energy flows in and out. But even a 2% error in readings can cost thousands of rupees each month. Accurate meters ensure: Fair billing: You only pay for the power you actually use. Energy efficiency tracking: Reliable data helps measure savings from your efficiency initiatives. Compliance: Many standards and regulators require verified meters. Sustainability reporting: Accurate data supports carbon footprint assessments and ESG goals. ISO 50001 certification: The standard specifically requires calibrated and verified measurement equipment. Simply put, when your energy meter is off, everything from power quality analysis to cost reporting becomes unreliable. What Is Field Energy Meter Calibration? Field calibration is the process of checking and verifying an energy meter’s accuracy on-site, without removing it from service. At Vibhawa, we use IEC-compliant Class 0.05 field calibrators, the same standard used internationally for high-precision verification. This ensures the process is both safe and highly accurate. Our engineers perform a series of non-intrusive tests, including voltage, current, power factor, and frequency checks, while your facility continues to operate normally. Learn more about our testing and commissioning services to see how we ensure system reliability across all energy infrastructure projects. Following International Standards (IEC Framework) We follow key International Electrotechnical Commission (IEC) standards as follows to ensure your meters meet global accuracy benchmarks: IEC 62052-11: Defines general requirements and environmental conditions for energy meter testing. IEC 62053 Series: Specifies accuracy classes for meters (Class 0.2S, 0.5S, 1, and 2). IEC 60736: Covers reference standards and testing equipment, ensuring calibration tools are significantly more accurate than the meters being tested. By following these frameworks, we, at Vibhawa, ensure traceable, certified, and internationally compliant calibration results, the same level of assurance demanded by energy regulators and industrial clients worldwide. Here’s a Step-by-Step Guide on How Field Calibration Works As mentioned above, our calibration process is designed for accuracy, transparency, and minimal disruption. And most importantly without any down time! 1. Pre-Calibration Preparation: We review meter specifications, prepare customized test protocols (to suit different energy meters/brands/models), and coordinate with your facility team for safe access. 2. Ambient Condition Verification: Field conditions like temperature and humidity are verified using integrated sensors to ensure compliance with IEC standards. 3. Non-Intrusive Connection: We test meters while they remain fully operational using precision voltage tapping and clamp-on current transformers. 4. Testing at Multiple Loads: We simulate various load points (from 5% to 100%) and power factors to confirm the meter’s accuracy across real-world operating conditions. 5. Error Analysis & Reporting: The results are then compared with the calibrator’s reference data. Any deviation is calculated, analyzed, and documented. 6. Certification & Recommendations: A full report is issued, including environmental conditions, error percentages, and compliance verification. The Real Benefits of Field Calibration Regular field calibration provides both technical and financial advantages: Zero Downtime: Meters stay in service during testing. Accurate Results: Tests are conducted in real operating conditions. Cost Efficiency: No need for meter removal or transport. Early Fault Detection: Identifies wiring or transformer issues early. Compliance Support: Helps maintain ISO 50001 and regulatory standards. Together, these benefits help companies optimize their energy management systems (EnMS) and build a stronger foundation for sustainability. ISO 50001 and Calibration Requirements Remember, if your organization is pursuing ISO 50001 Energy Management System certification, calibration is not optional; it’s a must. The standard requires that all measurement equipment be calibrated and verified periodically, with proper records maintained. We help clients achieve this with condition monitoring services and maintain compliance by providing: Detailed calibration documentation and traceability reports.
