Phase Sequence Indicators

Nortonics Phase Sequence Indicators (P.S.I.) are suitable for a range of applications to indicate both the presence of all three phases and the correct sequence of those phases.

Incorrect phase connection will often cause serious damage to the motors of compressors, pumps, gen-sets, heating and ventilation equipment. Mobile generators, remote installations and shore to ship supplies are most vulnerable to such hazzards and are, therefore, ideal applications for Nortonics range of P.S.I.

The absence of a phase is indicated by and a neon and the missing phase is identified. The presence of all three phases in the correct sequence is indicated by the white neon. Incorrect phase sequence is indicated by a red neon.
