without any theoretical calculations, can u approximately
tell the current rating of a motor(above 30hp)working at 415VAC.
Answer Posted / yogender goel
As per the Thumb Rule,
Current = (Motor HP x 1.5)-10% of the total
Example: If we want to calculate the current of the 100Hp
motor then
current = (100 x 1.5)-10% = 150-15 = 135 Amp.
