What is the total KVA?

Question

The following are my reading thru my multitester. Line voltage is 480V/277V,3ph,3w system

Line A= 87Amps

Line B= 77Amps

Line C= 55Amps

Phase AB= 477 Volts

Phase BC= 483 Volts

Phase AC= 475 Volts

What should be my Total KVA?

Answer 1

Since your line current and  voltages are unbalanced, get the average current, I =73 and the average line voltage = 478.33.

The average KVA = 1.732(V)I/10000

                  KVA = 21.732(478.33)73/1000

                   KVA= 60.48
