Phase Comparators - Pfisterer

Pfisterer Electrical Safety Equipment

Phase Comparators IEC 61481 - 3.3kV to 33kV Voltages

 

Pfisterer range of phase comparators are used for medium-high voltage installations and are used to check the phase coincidence in three-phase networks.

Single-pole phase comparators are of the same construction as the Pfisterer range of voltage detectors which ensures a high level of both safety and reliability. Phase comparison takes place using a single-pole phase comparator (SPPC) and contact being made between both conductors one after the other.

Pfisterer Single-pole Phase Comparator Technical Description

• Available for nominal voltages and nominal voltage ranges from 3 to 3 kV 
• Can be used with a rated frequency of 50 Hz
• For reliable phase comparison, a rated frequency of 49.9 - 50.1 Hz is required, with a maximum frequency drift of 10 mHz/s
• Self-test feature
• Automatic switch-off device
• Green, red and yellow LED display
• Removable contact electrode top piece, as forked electrode
