Digital HV Phasing Indicator with Digital Reading for use on Systems up to 33kV (109A913)
109A913
PR33D
The Seaward Group PR33D (109A913) Digital Reading HV Phasing Unit (33 kV) enables phase angle comparison on earth neutral systems up to 15 kilovolts. This unit provides voltage measurements and is supplied with a detachable earth leg which allows the digital leg to be used as a voltage indicator independent from the phasing leg.
Maximum Voltage: 33 kV
Resolution: 100V

The Seaward Group 109A913 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.
