Transformer Testing || DC Resistance Test of Transformer

[@surendrakverma555]

Very good. Thanks 🙏🙏🙏🙏🙏🙏🙏

Respected Sir,
Why short HV and LV 3-phase
Why not take seperate phase wise tan Delta?
What is impact on trasformer?

Thank you Sir from Algeria! qst: why wen we measure the resistance of transformer for second time, the result it's not same?

[@relayprotectionelectrical]

Yes. It it because it's depends on temperature. Have you noted down the temperature in oti or wti indicator? As temperature is different therefore winding resistance is different.
