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.
Answers were Sorted based on User's Feedback
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

1 Answers Delite Systems Engineering,
sir what is the purpose of SF6 in HT breaker and what is the pressure should be maintain in the breaker?
any body can give me idea or sketch of fuel(Diesel) level controller for genset.
i heard that power factor(PF) is the main concern for industries, if they are maintaining PF around 0.6 they will be fined for that. now the question is, how can they improve the PF ranging between 0.9 to 0.95 which is safe for them i,e escaping from the fine?
