Testing & commissioning, to energisation
Pre-commissioning tests, protection checks and energisation support for substations, transformers and battery storage plants, with a complete test record set at handover.
Overview
What we do
Equipment is only as good as the checks done before it is energised. Our testing team carries out pre-commissioning tests on transformers, switchgear, protection and cables, and supports the client and OEM through energisation.
We have tested and maintained transformers for NTPC, Azure Power and Accinova, and supported commissioning at the Kalasar BESS and at 400 kV and 220 kV grid substations.
Every job ends with test reports and as-built records prepared to client and owner's-engineer standards.

Questions
Testing & Commissioning FAQ
Do you have your own test equipment?
Yes. We use our own calibrated test instruments and our own oil filtration and vacuum plant.
Can you test equipment installed by others?
Yes. We take up testing and commissioning as a separate scope, including transformers and switchgear installed by other contractors.
What do we receive at handover?
A complete set of test reports and as-built records, prepared to client and owner's-engineer standards.
