Protection of induction motors against single phasing or reverse phasing or unbalance supply is one of the major problems in electrical systems. For safe running of 3-phase motors, special protections that keep a continuous watch on supply conditions are very essentials. The major cause of maxium motors burn-out is overloading which occurs due to unbalance supply or single phasing. Phase failure occurs in case of fuse blown-off, loose connections or loss of phase from supply itself.

We are offering pump protection relays. These relays are useful for protection of 3-phase ac induction motors against various hazards. With their unique advantages they eliminate use of a thermalbimetal relay for motor protection. Being current sensing, they are to be selected according to motor rating and are available for practically all ranges of motors. These relays are ideally suitable for air-conditioning compressor motor protection, as also for motors in machines, conveyors, craneshoists and lifts, and for pumps.

Protection of 3 Phase devices against Over voltage, Under voltage,Single Phasing, 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. VMR3P detects such Conditions & protect the load from burn out. PROTON's VMR 3P' offer above protections along with 3 digit display showing R-Y,Y-B,BR voltages in scanning mode with precise accuracy. LOWHIGH voltage tripping to ensure trouble free running of 3-phase Loads.

The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over-current, over-voltage, reverse power flow, over- and under- frequency. Microprocessor-based digital protection relays now emulate the original devices, as well as providing types of protection and supervision impractical with electromechanical relays. In many cases a single microprocessor relay provides functions that would take two or more electromechanical devices. By combining several functions in one case, numerical relays also save capital cost and maintenance cost over electromechanical relays. However, due to their very long life span, tens of thousands of these "silent sentinels" are still protecting transmission lines and electrical apparatus all over the world. An important transmission line or generator unit will have cubicles dedicated to protection, with many individual electromechanical devices, or one or two microprocessor relays.
