how will i find Transformer rating if supply voltage is 11k.v and how will i find incomer if transformer rating is 12MVA
3 5039Sir, I need a power supply at 380V. The supply I get in three phase is rated 415V. The total supply I have from the supply company is 70KW. Kindly inform if it is better to use a voltage stabiliser for this purpose or a transformer
