How can we measure MVAR of a 3 phase transformer.....???
When connecting CT secondary of R phase to watt meter
Current coil, and pressure coil connecting with PT
Secondary of remaining Y and B phase. The watt meter will
represent the MVAR oh Transformer....
I think it was my right answer. Guys if you are agree
With my answer please response.

Define steady state error.
What is the important precuations need tocarried out while working with Electrolite in Battery PM?
We have 2 Nos. Transformer with the capacity of 2000KVA and 1250 KVA and currently using only one 2000KVA T/R during operational hours while non- operational hous 1250 KVA T/R also used to reduce T & D losses. Similarly, 2 capacitor bank of 500KVAR and 300 KVAR also installed to balance reactive power. Now problem is around 1000 KW load PF is not maintaning 0.99 as 350 KVAR capacitor is in healty condtion. Now the PF is maintain 0.95 to 0.96.
Apparent power is expressed as V * I(Conjugate). Why not in V * I ?
