The method of detection of incomplete-phase operation of electrical equipment.
Abstract
The method is based on the phenomenon of a six-pulsation rectified voltage with a three-phase network and a four-pulse with a two-phase into a two-half-wave when a single-phase mode occurs. The two-transistor device that implements this method is simple; . The method of calculation and the scheme of a device designed to control a three-phase network with a voltage of 200 V. The power consumption does not exceed 4.5 W. The operating temperature range is from -10 ° to + 70 ° C. The device's performance is confirmed by the normal operation of more than 500 of its samples.
