它们可能因系统充电电流而错误跳闸。可根据要求提供磁性接地故障继电器。F5 GE Limitamp®中压电机控制保护和控制F欠压保护NEMA将欠压保护定义为一种主要目的是防止设备自动重启的设备。瞬时欠压保护是标准3线控制电路固有的,因为接触器会断开并保持在失压状态。延时可为Limitamp控制器提供延时欠压保护(TDUV),以防止电机在可调持续时间电压降低于可调电压降时停机。通过延时或标准瞬时欠压保护,电机保持断开状态,直到操作员重新启动电机。自动重启GE提供了一个自动重启继电器,可在瞬时断电后自动重启电机。它还可以设置为在电源恢复后延迟接触器重合闸,以便电机不会因剩余磁场或笼型转子电流而重新通电异相。穿越此可选功能提供控制,通过长达20个周期的瞬时控制电压中断,将标准电保持接触器保持在闭合位置They could trip falsely on systemcharging current. A magnetic ground-fault relay can be provided on request. F5 GE Limitamp® Medium Voltage Motor Control Protection & Control F Undervoltage Protection NEMA defines undervoltage protection as a device whose principal objective is to prevent automatic restarting of equipment. Instantaneous undervoltage protection is inherent to the standard 3-wire control circuits, since the contactor will drop out and stay out on loss of voltage. Time-Delay Time delay undervoltage protection (TDUV) for a Limitamp controller can be provided to prevent shut-down of a motor on adjustable duration voltage dips below the adjustable dropout voltage. With either time-delay or the standard instantaneous undervoltage protection, the motor remains disconnected until the operator restarts the motor. Automatic Restart GE offers an auto-restart relay which automatically restarts the motor following a momentary outage. It also can be set to delay contactor reclosure following power restoration so the motor is not re-energized out-of-phase due to residual field or cage rotor currents, Ride Through This optional feature provides control to maintain a standard electrically-held contactor in the closed position through momentary control voltage outages up to 20 cycles
