Rare video in Tamil on IR testing of DT transformers. Good point = No need of jumpering terminals.

while primary testing time secondary should be shorted & earthed & secondary IR doing time primary should be earthed..those details not informed sir..just for information.

It will be measured with Transformer ohm meter. By testing with multimeter you will get continuity (only beep) in secondary LV sides and a small ohm value on primary HV side but no beep.

megger.com/10-a-transformer-ohmmeter-mto210 The Transformer Ohmmeter is extremely useful when testing the windings and contact resistance of tap-changers with “make-before-break” contacts and voltage regulators. This action will check for pitted or misaligned contacts as the instrument will give an indication if either condition occurs.

For 11 kv transformer, cable, VCB, OCB We have to give only 5000 V DC is enough. For LT 500 V DC is enough to find the IR Value
