Seaward PR33D/PH3 Phasing Unit is designed to provide phase comparison at the point of paralleling two circuits, without the need for voltage transformers or secondary wiring circuits. It will also indicate if voltage is present and provide a measurement reading. The phasing and digital legs make up the set. Supplied with detachable earthing lead which allows the digital leg to act as a voltage meter without the use of the phasing leg.  Suitable for earthed neutral circuits up to 33kV. Supplied with calibration certificate.

The digital rod comprises of an integral rechargeable battery, supplied with charger and H3 proving unit, to test operation before and after deployment. Like all models in the series the PR33D is constructed from high grade PVC tubing and include encapsulated resistor chains.
