SRDF频率电压检测继电器是以电压为输入量并对输入量的频率和电压进行检测并显示，同时做出相应动作的一种继电器。通过检测两输入端电源频率差值及电压差值，将测得差值与设定值进行比较，而进行控制的继电器，频率检测值和电压检测值可在产品启动后进入菜单自行设置。频率电压检查继电器可应用于需要频率监控和电压监控(如发电机、变压器和输电线的继电保护等)的场合。
Frequency/Voltage Check Relay is one that activates upon measurement and display of the frequency of input voltage and voltage. The differences of frequencies and voltages at both ends of power supply are measured
and compared with the values preset and the frequency/voltage check relay is activated to monitor and control frequencies and voltages of appliances such as generator, transformer and power supply lines. The values limits for the frequencies and voltages can be set by the users themselves at the menu after the relay is switched on.
