Electrical consultancy and independent design review
From a 33 kV intake for a cement plant to the low-voltage and control systems of a resort, Vibhawa provides electrical design, independent review of someone else's design, protection and automation scheme design, and root-cause investigation when something has already gone wrong. Led by Chartered Electrical Engineers who also test and commission — so the design is written by people who know what fails on site.

What our electrical consultancy covers
Design work and advisory work across the full voltage range. The modelling and studies that often sit alongside it — protection coordination, arc flash, load flow, short circuit — are a service line of their own: Power System Studies.
High and medium voltage systemsSubstation and switchyard design to 33 kV, transformer and switchgear specification, cable sizing and routing, and the electrical design of generation plant — solar, wind, waste-to-energy, fuel cell — from the point of connection down.
Low voltage and extra-low voltageDistribution design for industrial, commercial and hospitality buildings, and the ELV systems around them: SCADA, building management, fire detection, data networks and CCTV. Specified so the contractor cannot misread it.
Lightning protection, surge protection and earthingRisk assessment and design to IEC 62305, earthing system design and the surge protection coordination most installations get wrong by buying the biggest device in the catalogue. On existing buildings we also test lightning protection and earthing.
Protection and automation scheme designThe relay scheme, the CT and VT specification, the interlocks and the settings philosophy for a plant or a generation site — written so the settings can be proven in a coordination study and tested at commissioning — see protection system testing.
Independent design reviewA second pair of eyes on a contractor's or an EPC's electrical design before it is built. Fault levels, protection, cable sizing, earthing, compliance with the standard the contract names. The cheapest moment to find a problem is before concrete is poured. More on our electrical design services.
Electrical incident investigationRoot-cause investigation after a fire, a failure or an injury — what happened, in what order, and what has to change so it does not happen again. Written to stand up in front of an insurer or a regulator — and, where the cause is wider than one fault, followed by an electrical safety audit.

How an engagement runs
01
Scope
A conversation about the project and what the engagement has to produce — a design, a review of someone else's, a scheme, or an answer to what went wrong.
02
Data and site
Drawings, loads, utility data and the standards the contract names. A site visit where the scope needs one — a review of an existing installation usually does, a new design from drawings usually does not.
03
Design or analysis
The engineering, in ETAP where modelling is involved, against the standard you are being held to: IEC, BS 7671, AS/NZS 3000 or the client specification.
04
Deliverable
Drawings, specifications, a review report with numbered findings, or an investigation report — signed by a Chartered Electrical Engineer and written to be acted on, not filed.

Frequently asked
What electrical consultancy does Vibhawa provide?
Electrical design for HV, MV, LV and ELV systems; independent review of a contractor's or EPC's design; protection and automation scheme design; lightning protection, surge and earthing design; and electrical incident investigation. Power system studies — coordination, arc flash, load flow, short circuit — are a separate service line and are often scoped together with design work.
Do you provide consultancy for renewable energy projects?
Yes — the electrical design of solar, wind, waste-to-energy and fuel-cell plant from the point of connection down, and the ETAP studies that go with it. We do not currently offer dynamic grid-code compliance modelling for utility connection applications, and we will say so rather than sell it.
Can you review or design a facility's protection scheme?
Yes. We design protection and automation schemes for plants and generation sites, and we review existing schemes through a protection coordination study. The design side writes the philosophy; the study side proves it on a model — and gives you the arc flash study from the same model; the testing side proves it on the switchgear. All three are in-house.
What is an independent design review, and when is it worth it?
A review of an electrical design produced by someone with a commercial interest in it being approved. It is worth it on any project where the contractor also chose the equipment, and on any project an insurer or a lender will look at. The finding that pays for the review is usually a fault level or a protection setting that would have been found at commissioning — at ten times the cost.
Do you work on projects outside Sri Lanka?
Yes. Design and modelling work is delivered remotely for clients in Australia, Vietnam and the UK, and we have delivered projects on site in the Maldives and Qatar. The same engineers lead the work wherever it is.
