逆功率继电器的可靠性直接关系到大中型发电机变压器组的安全运行。
Reliability of reverse-power relay is of immediate effect on the secure operation of large and medium generator-transformer units.
逆功率继电器逆功率继电器是指带瓦特计的继电器，用来感知电流的方向。
Reverse power relay a reverse power relay is a relay with a wattmeter movement that senses the direction of power flow.
如果一台发电机组没有运转，并且没有逆功率继电器保护，运转的机组就会驱动这个机组，这台机组上的发电机则变成电动机运行。
If one set stops and reverse power protection is not provided, the set still running will drive the set that has stopped. The generator on the set that has stopped will act as a motor.
