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.

- First of all, you need to look for a reliable ERDA approved transformer manufacturer and supplier.
- Choosing right place to buy a ERDA approved transformer from and maintaining it is as important as taking care of our assets, so next time your industrial transformer has a problem making sure you go to the right place.
- Check if the manufacturer offers customized transformers to meet your requirements so that you get a ERDA approved transformer best suited for the purpose you want to purchase it for.
- Check for the protection of the device you want to purchase, and ask the manufacturer for a guarantee.
- Test Report
- Test report will be issued for the equipment/products tested, at no extra cost, but only upon payment of the final bill of test charges. In case of requirement of additional copies of test report/test certificate, the Customer shall inform the Testing Authority before commencement of the test. Separate charges will be levied for such requests.
- The report will contain the record of the values of test results, the physical condition of the equipment/products during/after the test(s) copy(s) of Oscillogram(s), graphs, drawings, photographs, etc as appropriate.
- Test Certificate
