Why usually in all electrical equipment taking more current
in Y pahse like pumps,compressor,or any other applications
Is phase preventer require when overload relay is there
why we pefer the salient pole for synchronous motor ?
A three phase load, around 4 km away from the 11/0.433KV distribution transformer (Neutral of Transformer is solidily earthed) and consisting of mainly very costly and sensitive electronic equipments is giving trouble due to high voltage difference between neutral and body earth. Whether this problem can addressed by connecting neutral at the load point solidly to earth?
Where we use 30mA , 100mA & 300mA RCCB ?
