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.

'PROTONs MULTIFUNCTION RELAY - SPP 1' offer these protections along with LOW/HIGH voltage tripping to ensure the trouble free running of 3-phase motors.

 

Features


  • Operates on the principle of sensing negative sequence components of the system.

  • Suitable for the protections of motors of any H.P.

  • Protection against single phasing, reverse phasing, unbalance supply.

  • No separate auxiliary supply required.

  • Individual trip indication for SPP, reverse phasing and indication for output relay ON.

  • Auto reset type voltage hysterisis gap for tripping on under/over voltage.
