Phasing rods with digital reading for use on systems up to 33kV

- For use on earthed neutral systems up to 33kV
- Kit complete with Proving unit and Extension rods included
- LCD digital display
- Resin filled, robust construction to industry standards


The 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 PR33D features high-grade PVC tubing and incorporates totally encapsulated resistor chains.

Accessories are available, including 90º and 120º bent end adaptors for easy access to difficult to reach switchgear.

The PR33D covers a wide range of applications and voltages and is used in many industries such as Power generation, Sub-station maintenance and Switchgear maintenance.
