Polarity testing of Transformer

Polarity testing of Transformer
If Transformer Primary voltage has positive cycle then we need to find the secondary side voltage start from positive cycle or negative cycle.
In polarity we have two
Additive polarity &
Subtractive polarity

This is how a testing engineer will explain I have seen many videos everyone will explain using paper and pen. But sir your explained very clearly with practical thank you for this video sir. And I think next video will be transformer stability

Thanks and welcome

Thanks for your efforts to explain polarity test. I suggest you to make a diagram with your practical presentation. Diagram makes the concept more clear. Secondly there would have been more clarity if you explain it with vectors as we do in vector group verification.

[@abhishekra5990]

sir thanks for the video, which polarity is best ,add or subtract polarity? and generally which polarity they choose for power transformers with voltage ratio 400kv/110kv? and for distribution transformers with voltage ration 11kv/433v.thank you

Boss can we perform polarity test in auto transformers?

[@merajislam54]

Sir, For 1-phase transformer DVDF test, what is value of 3.46 ???? I hopeful that you will reply to my question. I am Waiting....

[@baranitech1026]

sorry i am not having ans for this i will check for you.

[@KarthiKeyan-uh5fw]

In transformers paralleling both transformers should be in which polarity sir...

[@baranitech1026]

both should have same polarity whether add or Subtractive. but choosing Subtractive is good .

[@Amu7574]

Please make one detailed video on OLTC wiring along with RTCC

okay bro .

How to find polarity of three phase Dyn11 ?

[@baranitech1026]

we have to go for vector test .

Sir it's good video sir how to test in 3 phase delta transformer and star transformer
