what is the formula for 3 phase motor starting cureent
deatials
3phase 148A delta 415v, efficiancy 94%
can we run the motor with 200A incoming supply
Answer Posted / prashant
P = 1.732VICosA
I = 148A
Starting current of a motor is 1.25 - 1.5% of I so you
should be able to run the motor but it will be preferable
if yu can go for the next higher rating
