Voltage Frequency Monitoring Relay
(VFR 3P) :
 
 
Voltage Frequency Monitoring Relay
 
Protection of 3 Phase devices against Over voltage, Under voltage, Single Phasing, Over Frequency, Under Frequency, Reverse Phasing & unbalance supply are one of the major issue in electrical systems. For 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. VFR3P detects such Conditions & protect the load from burn out. 'PROTON's VFR 3P' offer above protections along with 3 digit display showing R-Y,Y-B,BR voltages in scanning mode with precise accuracy.

LOW/HIGH voltage tripping to ensure trouble free running of 3-phase Loads, And also protection is provided against Over /Under Frequency
