Radio Interference Radio interference refers to the interference with radio reception caused by a generator set.
无线电干扰 无线电干扰是指发电机组对无线电信号接收造成的干扰。

Reactive Power Reactive power is power that flows back and forth between the inductive windings of the generator and the inductive windings of motors, transformers, etc., which are part of the electrical load. This power does no useful work in the electrical load nor does it present load to the engine. It does apply load to the generator and limits the capacity of the generator.
无功功率 无功功率是指电流在发电机、电动机、变压器等的感应线圈之间往复流动，这也构成了电力负载的一部分。它并没做有用功，而且也不是发动机的负载，但是作为发电机负载，限制了发电机的容量。

Reverse Power Relay A reverse power relay is a relay with a wattmeter movement that senses the direction of power flow. In paralleled sets, a flow of reverse power (i.e., power flow into set) will actuate the reverse power relay and disconnect the set from the system. 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.
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。在并联机组中，反方向电流（例如流回发电机组的电流）会启动逆功率继电器，把该机组与系统断开。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。
