1. Functions and applications
1).funtions
Â
RD*-W 3 phases voltage monitoring relay is used to test 3 phase power, protect electric machine and other loading. Voltage display, over voltage and under voltage protection, phase protection, phase loss protection, counting and timing. Record the fauits times and timing.
Â
 2).Applications
Avoid the danger of the reverse operation(lifts, transports, elevators, escalators, ect.)
The sensitive three-phase power control.Â
Prevent the risk of transmission load(phase loss)
Switch for normal and emergent power
Â
2.Working principle
1).Connect the three phases to terminals L1,L2, L3.No need for
extra power supply for the phase relays. It is powered by the three
terminals.
Â
Â
2).When the terminals are conducted, relays pull-in voltage, LED lights and it will show the current voltage. if the phases are correct and each voltage is correspond to what has been set.
Â
When over voltage, the relay is off. It shows Over voltage on LCD in English.
When under voltage, the relay is off. It shows under voltage on LCD in English.
