Fundamental component onlyAssumes phase currents at equal fundamental frequency and ideal phase angles. Triplen harmonics, phase-angle displacement, neutral impedance, and actual waveform measurements are excluded.
About this calculator
Estimate fundamental neutral current by phasor-summing supported split-phase or three-phase wye load currents.
Method and assumptions
For split-phase systems the phase currents are 180° apart. For three-phase wye systems they are spaced 120° apart. The calculator sums the current phasors and reports their resultant magnitude.
It does not estimate harmonic neutral loading or establish conductor ampacity.
