Does dry and oil transformers both require dedicated neutral, because in my project we are using 2500kv dry star delta transformer, where they say neutral not required and even it is not provided in our substation. can u let me know
Answer Posted / mohitsaran
Yes, We need 02 Nos. Neutral Earthing for Both DG and Transformer Sets.
Neutral Earthing are required to balanced the unbalanced current due to load variations.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened.
