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...
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....
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...
