WebThe neutral current can be determined by adding the three phase currents together as complex numbers and then converting from rectangular to polar co-ordinates. If the three-phase root mean square (RMS) currents are I L 1 {\displaystyle I_{L1}} , I L 2 {\displaystyle I_{L2}} , and I L 3 {\displaystyle I_{L3}} , the neutral RMS current is: WebScore: 4.5/5 (30 votes) . For any single-phase AC circuit, Current, I = 1000 x kW / (Vac x P.F.) Therefore, amps can be calculated from AC – kW by dividing kW by the product of the RMS value of applied AC voltage and power factor and multiplying it by 1000.
