Seaward HV Phasing Units

The PR11 provides a means of phase comparison at the point of paralleling two circuits, without the interposition of voltage transformers or secondary wiring earthed neutral systems.

A neon type instrument, it is designed for use on earthed neutral systems up to 11KV. The PR15D / PR33D units enable phase angle comparison on earthed neutral systems up to 15KV and 33KV respectively.

The digital reading instruments provide voltage measurements and are supplied with detatchable earth lead, allowing the digital leg to be used as a voltage indicator, independently from the phasing leg.

PR11 Features

  For use on 1kV to 11.5kV systems
  PVC hand guards on handles of elements
  Neon indicator enclosed in shock resistant sleeve
  Direct areas possible to all types of switch gear
  Complies with UK Electricity Council Engineering recommendation G9

PR15D/PR33D Features

  Provides a means of phase angle comparison and indication of phase angle voltage at the point of intended paralleling of two circuits on neutral earthed systems. Both units are digital instruments
  Chart provides a means of checking phase angle difference of circuits paralleled
  Kit comprises two elements with resistor chains, one with digital indicator and the second a phasing rod
