how to calculate the input current in singel phase and
3phase supply to 5kva ups
Answer / h s dhillon
Let the supply is 3 ph 4 w having line voltage 400 volts
and phase voltage 230 volts,then:
in case of single phase:
I=5000/230=21.74 Amp
In case of 3 phase:
I=5000/Under root3 i.e.1.732x400
=7.22 Amp
