The total power loss in a transformer (i.e core loss/iron loss + copper loss) can be determined using Sumpner Test ( also called as Back to Back circuit Test )

Good job, you have authentic kind of equipments to teach the topic. It's a admirable thing. Keep it up. 😊

What do you understand by step up transformer
Answer . output voltage is higher than input is called step up

[@padalajyothi4335]

Sumpner's test on pair of two identical Transformers

[@bharttruhari0714]

Thanku sir

[@devanesh5791]

great!!!!!

[@samalaparusharam4073]

I think sumpners test for finding both losses

[@pankajsanwal2010]

Sir I am seeking a video on , no load consumption test of any transformer . I mean how I calculate it perfectly. I hope you will include this topic,Thank you.

[@shrutimukherjee8378]

Please tell the readings of sc test

What type of single phase transformer did you use?

[@KaviyadeviSankaran]

Direct load test
