Protection of 3 Phase devices against Over voltage, Under voltage,(UB) Single Phasing,(SPP) Over Frequency, Under Frequency, Reverse Phasing & Unbalance supply are one of the major issues 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 or Reverse phasing conditions. VFR3P detects such conditions & protects the load from the burn out. 'Proton's VFR 3P' offers above protections along with 3 digit display showing R-Y,Y-B,B-R, voltages in scanning mode with precise accuracy. LowHigh voltage tripping to ensures trouble free running of 3-phase Loads, and also protection is provided against Over Under Frequency
