Seaward PR11-50/PH3 High Voltage Phasing Sticks

The Seaward PR11-50 Phasing Sticks provide a means of phase comparison at the point of paralleling two circuits without the use of voltage transformers or secondary wiring circuits. The PR11-50 HV neon phasing unit is designed for use on earthed neutral circuits from 3.3kV to 11KV. These phasing sticks are provided with 3mm wide tips for accessing narrow points on switch gear. In addition a PH3 High Voltage Proving Unit is included to prove the operation of voltage indicators before and after use. This product is often called "Phase Comparator Sticks".
