Quality & testing

Every unit is routine-tested before it leaves the floor.

Quality assurance is not a department here — it is the reason we kept testing in-house. Design, winding, assembly, oil filtration and high-voltage testing all happen under one roof in Vadodara, which is why we can stand behind every test certificate we issue.

Quality assurance

How we hold the standard.

Reliability of design, a zero-failure aim, and strict adherence to laid-down quality-system standards — applied at every stage rather than checked at the end.

Design review

Magnetic circuit, windings, insulation, losses, impedance and short-circuit forces calculated to IS 2026 and IEC 60076 before any material is cut.

Incoming material check

CRGO laminations, conductor and insulating material inspected on arrival. A transformer is only as good as what goes into it.

In-process inspection

Coil clamping, core-coil assembly, tanking and brazing checked stage by stage on our own floor, not signed off at the end.

Oil filtration

Filtered through our 4.5 KL mobile plant to the required breakdown voltage before and after tanking.

Routine and type testing

Every unit routine-tested to IS 2026 in our own 33 kV bay. Type tests performed on request.

Documented and traceable

Each unit ships with its routine test certificate, GA drawing and rating plate details — the paperwork an inspector asks for.

In-house testing

The test bay, and what it proves.

Testing in-house is the difference between a delivery date we control and one we hope for. These are the facilities on our Vadodara floor.

Equipment / test	Range	Standard	What it proves
High-voltage test bay	up to 33 kV	IS 2026	Routine and type testing of oil-immersed transformers on our own floor.
Ratio, polarity and vector group test	All ratings	IS 2026	Confirms the unit is wound and connected exactly to the approved design.
Winding resistance measurement	All ratings	IS 2026	Detects a poor joint or a wrong turn count before the unit is tanked.
No-load and load loss measurement	up to 8000 KVA	IS 2026	The losses a buyer is contractually paying for, measured rather than quoted.
Insulation resistance and HV withstand	up to 33 kV	IS 2026	Proves the insulation system holds at the specified voltage class.
Mobile oil filtration plant	4.5 KL	IS 1866	Runs on our floor or at your site during installation and commissioning.
Overhead crane	15 tons	—	Handles core-coil assemblies and tanked units without external lifting hire.
Winding machines	to 12 tons	—	Spiral, cross-over, helical and continuous disc windings wound in-house.

A routine test certificate accompanies every unit dispatched. Type test reports and witnessed testing are available on request — tell us at the enquiry stage so we can schedule the bay.
