The Seaward PR11 Live Line Tester provides a means of phase comparison at the point of paralleling two circuits.
Comes complete with a calibration Certificate Traceable to National Standards when purchased new.
The Seaward PR11 Live Line Tester 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, Seaward PR11 Live Line Tester 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.
