Phase Comparators MV HV 11kV 33kV

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

Single-pole phase comparators of type SPPC have the same construction as Pfisterer voltage detectors. This ensures a high level of both safety and reliability. Phase comparison takes place using a single-pole phase comparator SPPC, and making contact with both conductors one after the other.

Single-pole Phase Comparator SPPC – available for various nominal voltages an voltage ranges
Single-pole Phase Comparator SPPC, Switchable – can switch between three nominal voltage ranges using the voltage range switching ring

11kV Phase Comparator

Deltameter 5 is a measuring device suitable for indicating the voltage difference between two phases. The Phase Comparator is tested with IEC 61481 providing a highly precise decision making tool for imminent switching operations.
