Answer / jaykaran gadhvi
the answer is
line current =kva( 3 phase) / (sqrt(3)* line voltage in kv)
so
kva ( 3 phase) = sqrt(3)* line voltage in kv * ampere

Answer / joseph
You can use the basic formula:
VA = [Voltage X 1.732] * Current
or
VA = [Voltage * 1.732] * I
Hence, VA of a 3 Phase system with 1500A Current current at
440V will be:
VA = [440 * 1.732] * 1500
= 1143120 VA or 1143 KVA.

Answer / v.chandrasekharreddy
Amps when
kVA is known ,I=KVA*1000/[1.732*VOLTAGE]IN THREE PHASE
Amps when
kVA is known
I=kVA x 1000/VOLTAGE SINGLE PHASE

Answer / p.baskar
Amps =KVA*1000/[1.732*VOLTAGE]IN THREE PHASE
Amps =kVA x 1000/VOLTAGE SINGLE PHASE

Answer / thebalu007
kw = Route that mean 1.732*v*i*cosPai
I = route that mean 1.732*V
because kva does not having power factor that men cos pai

Answer / dinesh jakhar
Apparent power =V.A
Unit of apparent power is VA or KVA or MVA
So if you want to find KVA simple formula u just need voltage and current
kVA= KV(voltage) * A (current)

11KW Delta motor is taking about 44Amps in star and goes upto 70Amps in delta and trips OFF. The rated current is 26Amps. Application is for the blower. The motor takes ( no load without coupling impller ) only 2.5A and 5Amps in star & delta starter test.Need to know why its taking high current.
