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. It is suitable for use on earthed neutral systems up to 33kV. The LCD display is powered by an integral rechargeable battery and is supplied complete with battery charger and PH3 proving unit in a bespoke carrying case. Conforming to recommended, creepage and safety standards, the Seaward PR33D features high-grade PVC tubing and incorporates totally encapsulated resistor chains.
