Seaward PR11-50 HV Phasing Unit & PH3

The Seaward PR11 Phasing Sticks have been designed to provide a means of phase comparison at the point of paralleling two circuits, without the interposition of voltage transformers or secondary wiring circuits. As a neon instrument, it is designed for use on earthed neutral circuits up to 11KV.

This pair of phasing sticks come with a 3mm wide tip for accessing narrow points on switch gear. Also included in this set is a Seaward PH3 Proving Unit.
