 过电流继电器，简称CO，是从电流**过其设定值而动作的继电器，可做系统线路及过载的保护用，较常用的是感应型过电流继电器，是利用电磁铁与铝或铜制的旋转盘相对，依靠电磁感应原理使旋转圆盘转动，以达到保护作用。

动作原理：

感应型过电流继电器是利用电流互感器二次侧电流，在继电器内产生磁场，以促使圆盘转动，但流过的电流必须大于电流标置板的电流值才能转动。

2、过电压继电器

过电压继电器，简称OV，它的主要用途在于当系统的异常电压上升至120%额定值以上时，过电压继电器动作而使断路器跳脱保护电力设备免遭损坏，感应式过电压继电器的构造及动作原理和过电流继电器相似，只有主线圈不同。

3、欠电压继电器

欠电压继电器，简称UV，其构造与过电压继电器相同，所不同的是内部触头及当外加电压时转盘会立即转动。

4、接地过电压继电器

接地过电压继电器，简称OVG，或称接地报警继电器简称GR，其构造与过电压继电器相同，使用与三相三线非接地系统，接于开口三角形接地的接地互感器上，用以检知零相电压。GENERAL ELECTRIC DS3800DXRA1C1C 6BA04 SIGNAL RECEIVER CARD SERIES 6 DXRA 6DA03
