HUVT系列数显电压继电器主要用于继电保护线路中，作为欠电压或过电压监视的动作元件。
报警电压值可在产品启动后进入菜单自行设置，且每相报警电压设定值设置相互独立。辅助电源
电压一经馈入，绿色电源指示灯亮，将被测电压和设定值进行比较，若被监测电压任意一相达到
报警状态，红色报警指示灯闪烁提示报警，若被测电压在延时时间t内恢复，报警指示灯停止闪
烁，输出继电器保持复位状态;若超过设定的延时时间t，输入电压还未恢复，输出继电器置位。
当发生报警且输出继电器置位后，若所有被测电压又恢复到正常状态，此时红色报警指示灯
停止闪烁，输出继电器复位。
多路监视显示:U1灯亮，数码管显示U1端输入电压值;U2灯亮，数码管显示U2端输入电压值;
U3灯亮，数码管显示U3端输入电压值;电压显示10s自动切换一次，也可以手动按“①”和“①”键切换。
HUVT Series of Digital Display Voltage Relay is used as superv***ry action component for under or over voltage in lines
protected by relays.The voltage values for alarm can be set by the users in the setting menu whenthe relay is activated and
the alarm setting for each phase is independent from each other. With the input of auxiliary voltage, the green indicator is
lightened and the voltage detected is compared with the values set. If the detected voltage reaches the values for alarm, the
red indicator flashes and sends alarms. If the detected voltage resumes its normal value within the delay time of “t” , the
flash stops, and the output relay restore its normal position.If the delay time expires and the detected voltage remains
abnormal, the output relay trips.
After the alarm is sent and output relay trips, if all the detected voltages restore the normal values, the red indicator stops
flashing and the output relay restores its normal position.
Multiple Line Product: When indicator U1 is lightened, the LED displays the input voltage value at the U1 terminal; when
U2 is lightened, the LED displays the input voltage value at the U2 terminal; when U3 is lightened, the LED displays the input
voltage value at the U3 terminal. The display of voltage automatically changes at an
interval of 10s, and it can also be changed upon the press of buttons and .
