Seaward PR11 HV Neon Phasing Unit
Seaward's PR11 is a dual-probe phasing unit designed for use on high voltage systems from 1kV to 11.5kV.
Primarily designed for easy access to all types of switch gear, the PR11 gives the user the ability to carry out phase comparison at paralleling two circuits without the effects of voltage transformers or secondary wiring earthed neutral systems.
This phasing unit uses neon indicators to define what it has detected. The indicators are in a shock resistant sleeve for extra protection and the probes contain PVC hand guards for protection of the user.
The PR11 is compliant with UK Electricity Council Engineering recommendation G9.
