The Power trip unit continues to use GE's proven technique of measuring True RMS currents of both sinusoidal and harmonically distorted waveforms. The frequent sampling (48 times per cycle per phase) allows precise calculations of True RMS current. The sampling rate allows waveform measurements up to the 11th harmonic. True RMS sensing avoids potential under- or over-protection problems associated with peak-sensing tripping systems.
