How can we calculate the current if we have load in KVA and if
the load in KW then what formula will be use for calculating
the current. please give both the formula for calculating the
current.
Answer Posted / 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
