Abstract
PURPOSE: To detect the existence of phaselessness without being influenced by waveform distortion by connecting an effective value rectification circuit between the phase of a multi phase power supply to detect the inter-phase effective voltage and discriminating the existence of the phaselessness in accordance with its voltage by a compare detection circuit.
