Single Phase Preventer (SPP)

Single Phase Preventer (SPP)


Technic Electronic Corporation offers a Single Phase Preventer (SPP) specifically designed to protect motors from working in unfavourable conditions such as single phasing and unbalanced voltage. More than 90% of burn out of motors are caused by unbalanced voltage supply or phase failure. These faults are mostly undetected by conventional overload relays and due to which normal overload protection doesn’t trip on time. Thus there is a need for a single phase preventer, which senses true negative phase sequence and trips the motors. When wrong phase sequence is detected by the SPP, the motor is automatically switched off and thus prevents rotation of the motor in reverse direction. Technic SPP also provides a time delay feature of 2.5 sec ±0.5 sec to avoid false tripping. It can be used in any HP rated motor.
