Answer / soumen das biswas

For KVA rating,
The formula for determine the current is:

I = KVA/(1.732 x Voltage) (For three phase system)
I = KVA/Voltage (For Single Phase)

For KW rating
The Formula for current is

I= KW/(1.732 x Voltage x Power factor)(for three phase system)
I = KW/(Voltage X Power factor)(For Single Phase)

Answer / j.l. singh

If there is three phase system formula for the
KW = 1000.root3 VA cos Phi.
KVA = 1000 VA
V =Voltage A = Ampere.

Answer / denzel101

For KVA rating, the formuler for current will be:

I = KVA/(0.707 x Voltage) for three phase system

For KW rating

I= KW/(0.707 x Voltage x cos phi)
for three phase system
