Seaward PR33D/PH3 Digital Phasing Unit

The Seaward PR33D is a digital HV potential indicator and phasing stick which can be used to indicate the presence of voltage, make voltage measurements and provide a means of phase comparison at the point of paralleling two circuits, without the interposition of voltage transformers or secondary wiring circuits The PR33D potential indicator and phasing stick is suitable for use on earthed neutral systems up to between 3-33kV.

The LCD display on the digital leg is powered by an integral rechargeable battery and is supplied complete with battery charger and PH3 proving unit in a bespoke carrying case.

This robust, highly portable digital potential indicator and phasing stick is supplied with a carrying case for the indicator and accessories. Conforming in design lengths to recommended, creepage and safety standards, the PR series features high grade PVC tubing and incorporates totally encapsulated resistor chains.

Provides a means of phase angle comparison and indication of phase angle voltage at the point of intended paralleling of two circuits on neutral earthed systems.

  • Supplied with a quick reference chart for checking phase angle difference of circuits paralled.
  • Kit comprises two elements with resistor chains, one with digital indicator and the second a phasing rod
  • Bent adaptors available for use with switch gear
  • Indicator can be used independently as a voltmeter.
