Seaward PR33D HV Phasing Unit & PH3

description

technical info

The Seaward PR33D digital HV potential indicator and phasing stick 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 Seaward PR33D potential indicator and phasing stick is suitable for use on earthed neutral systems up to 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, and 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.
