Dear K.prakashchandra
Convincing answer, but I need to make sure
For the reason that there are those who say that the only
difference is that in var-hour meter voltage coils are Delta
connected .
And in kilo watt-hour meter voltage coils are star connected.
Please confirm information on the displacement of angle,
because I had read about it before.
thanks
