At Rajasthan Powergen Transformer P. Ltd., We are a factory that has been cpri approved transformers for various fields such as distributors transformers, power transformers, current transformers, reactors as well as voltage transformers. Since we are cpri approved transformers manufacturers, the reactors & transformers, produced in our factory have been tested periodically for both Impulse as well as Short circuit withstand. With regards to Distribution and Power Transformers, the tests administered according to the Central Power Research Institute standards include Short circuit dynamic and thermal withstands test.
Generally, the cpri approved transformers are tested with Short circuit tests up to 200 kArm or a 1100 Volts for LT equipment has been used or Short time current tests up to 200 kArms for one second or 100 kArms for a period of 3 seconds.As one of the leading cpri approved transformers manufacturers, we have facilities to test and check our products at regular intervals.We are one of the leading and certified dealers, suppliers and distributors along with being a cpri approved transformers manufacturers in Mumbai.

- 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
- The sealed test certificate is issued, on request and on payment of additional 10% of the total test charges when an equipment/product/sample of a particular type and rating has satisfactorily passed all the specified tests in compliance with the conditions stipulated in a published National/International Standards.
- This Certificate is issued in justification of the satisfactory rating of the equipment/product/sample for which it is tested.
