The protection of induction motors against a single reverse phasing or phasing or supply imbalance is one of the main problems in electrical systems. For the safe operation of three-phase motors, special protections that maintain a continuous monitoring of the supply conditions are very essential. The main cause of maximum burn-out motors is the overload that occurs due to the unbalance or single-phase supply. Phase failure occurs in case of a blown fuse, loose connections or phase loss of the power supply itself.
'PROTONs MULTIFUNCTION RELAY - SPP 1' offer these protections together with the LOW / HIGH voltage trip to guarantee trouble-free operation of three-phase motors. OUTSTANDING CHARACTERISTICS: • Works with the principle of detecting negative sequence components of the system. • Suitable for motor protection of any H.P. • Protection against single phasing, inverse phasing, supply of imbalance. • No separate auxiliary supply is required. • Individual trip indication for SPP, inverse phasing and indication for output relay ON. • Automatic reset type voltage hysteresis range for low voltage / surge voltage tripping. |
