The Seaward PR33D are high voltage (HV) phasing indicators / phasing sticks with digital readout display and suitable for voltage measurement up to 33kV.
Phasing sticks provide a means of phase comparison at the point of paralleling two circuits (i.e. matching L1, L2, and L3 phases to each other when joining cables or connecting motors as incorrect connection could result in the motor running in the opposite direction). Likewise, in a power distribution scenario, care should be taken that the correct phases are joined together.
Applications:
Power generation
Sub-station maintenance
Switchgear maintenance
The PR33D will indicate <900V on screen when the correct phasing is connected.
The kit comes supplied with a Proving Unit, battery charger, 2 x 1.5m straight extension rods, 3m earth lead and a carry case.
A range of accessories are available, including 90 and 120 degree bends and extension rods (sold separately).
