What Is a Voltage Detector?

The voltage monitor is a statistical voltage monitor that continuously monitors and statistics the voltage deviation caused by the slowly changing normal operating state of the power system. With functions of monitoring, analysis, memory, query, parameter setting, etc.

Voltage monitor

The voltage monitor is a statistical voltage monitor that continuously monitors and statistics the voltage deviation caused by the slowly changing normal operating state of the power system. With monitoring, analysis, memory, query, parameter setting and other functions, support

1. Real-time voltage display status: display date, time, instantaneous value and status of each voltage;

2.Menu status:

(1) Query the year / month / day statistics of each voltage, including: total operating time, average voltage, qualified time, qualified rate, over-limit time, over-limit rate, over-low limit time, over-low limit rate, maximum voltage The moment when the maximum voltage appears, the minimum voltage value, the moment when the minimum voltage appears, the number of power failures, and the total time of power loss;

(2) Query the voltage loss records of each channel, including: the moment of power loss and the moment of recovery. ^[1]
