The neutral time overcurrent element can provide a desired time-delay operating characteristic versus the applied current
or be used as a simple definite time element. The neutral current input value is a quantity calculated as 3Io from the phase
currents and may be programmed as fundamental phasor magnitude or total waveform RMS magnitude as required by the
application.
