The undervoltage protector is a multi-function three-phase three-wire power system or a three-phase power equipment monitoring and protection instrument. It integrates three-phase voltage display, over-voltage protection, under-voltage protection, phase loss protection (phase failure protection), three-phase voltage imbalance protection, and phase sequence protection (wrong phase protection). It can be used to monitor important parameters (voltage, phase sequence, phase loss, phase balance) in the three-phase power supply system. For the abnormal situation that the three-phase power supply may harm the safe and reliable operation of the power supply system and equipment, an alarm signal can be issued in time to control The system can be properly handled before the machine is damaged, resulting in maximum protection of the machine and system, improved machine, equipment and system availability, and reduced maintenance costs due to three-phase system failures.
