Testing

Before declaring a readiness of the transformer for service, it undergoes a series of tests categorised as below -

A. ROUTINE TESTS

	Measurement of insulation resistance of H.Y. & L.Y. windings
	Voltage ratio measurement & check of polarities (Phase relationship/vector group).
	Winding resistance measurement
	No load loss & No load current measurement
	Short circuit impedance & load loss measurement
	Induced over voltage test
	Separate source power frequency withstand test
	Di-electric value of oil

B. TYPE TESTS / SPECIAL TESTS

	Temperature rise test / Heat run test
	Impulse test*
	Dynamic short circuit withstand ability test*
	Unbalance current test
	Magnetic balance test
	Measurement of zero sequence impedance
	Measurement of noise level in accordance with IS : 1180 & IS : 2026

* To be carried out on specific demand of the customer. Our II kV Distribution Transformers up to 200 KVA are type tested at ERDA, Vadodara
