In any plant or substation main incommer voltage RY - 415
V,YB - 400 V, BR - 387 V(in commer feed from transformer 11
Kv /0.415 KV) why found voltage differance in each phase?
plant have not self power plant it is depend on outsource
grid

Answer Posted / kj

First check the 11kv is correct. If the 11kv is different
on each phase the LT side will also be different.
If 11 kv is OK and the voltage is different on no load the
fault is in transformer as answer above.
