Testing facilitiesOVERVIEW

Independent testing facilities for distribution and power transformers at both Lucknow and Sitarganj plant.

Fully automated, computerized test benches & advanced testing software for all routine tests and temperature rise tests as per international standards like IS 2026 and IEC 60076.

In-house facilities created for ALL routine tests, Type tests such as Temperature Rise & Impulse test, and specialised tests such as FRA, Noise & Vibration measurement, etc.

Short circuit tests are subjected to third party testing at CPRI (India’s leading, independent test centers).

Impulse voltage withstand ability tests are carried out through two impulse generators (1600 kVp, 160 kJ and 900 kVp, 45 kJ) from Haefely, Switzerland with expandable capacity to test transformers of 765 kV voltage class.
