电压继电器是一种常用的电磁式继电器，电压继电器用于电力拖动系统的电压保护和控制。其线圈并联接入主电路，感测主电路的线路电压；触点接于控制电路，为执行元件。按吸合电压的大小，电压继电器可分为过电压继电器和欠电压继电器。过电压继电器(FV)用于线路的过电压保护，其吸合整定值为被保护线路额定电1.05～1.2倍。当被保护的线路电压正常时，衔铁不动作；当被保护线路的电压高于额定值，达到过电压继电器的整定值时，衔铁吸合，触点机构动作，控制电路失电，控制接触器及时分断被保护电路。欠电压继电器(KV)用于线路的欠电压保护，其释放整定值为线路额定电压的0.1～0.6倍。当被保护线路电压正常时，衔铁可靠吸合；当被保护线路电压降至欠电压继电器的释放整定值时，衔铁释放，触点机构复位，控制接触器及时分断被保护电路。零电压继电器是当电路电压降低到5％～25％UN时释放，对电路实现零电压保护。用于线路的失压保护。中间继电器实质上是一种电压继电器。它的特点是触点数目较多，电流容量可增大，起到中间放大(触点数目和电流容量)的作用。
