Three Phase Voltage Monitoring Relay Protection of 3 Phase devices against Over voltage, Under voltage, Single Phasing, Reverse Phasing & unbalance supply are one of the major issues in electrical systems. For the safe running of 3-phase devices, special protections that keep a continuous watch on supply conditions are very essential. The major cause of maximum load burn-out is overloading which occurs due to unbalance supply, Single Phasing & Reverse Phasing conditions.
Q. What is a Phase Failure Relay?
Ans. These relays are suitable for monitoring incoming 3-phase supply from Mains (Electricity distribution line) they can be used for any HP/KW rating of load. These relays are suitable for monitoring incoming 3-phase supply from Mains (Electricity distribution line).

    Every time you switch of Y phase it's create confusions. One one time R Y B switch off so students can easily understand.

    It will work on every phase i switch off Y phase supply every time because my Starter works on 415 volt supply and if i switch off R or B Phase supply starter will turn off directly due to power cut But VMR works for each phase similarly
