These erda approved transformers have been expected to find an increased demand with huge emphasis placed on infrastructure development.Instrument Transformers such as both CTs as well as PTs have wide application in the power system which involve metering and protecting. Indigenously .

erda approved transformers manufacturers produce these transformers across a wide variety of ratings. Hence, these transformers which fall in the range of up to 160 MVA, 400 kV Class are required to pass several tests administered such as the Impulse Test, 4 MVA, 33 kV Class for short Circuit test as well as up to 2000 kVA 33 kV for routine tests can be tested.

We are one of the leading erda approved transformers manufacturers in India.
