Single-Pole Phase Comparators
Phase comparators for medium voltage are used to check phase coincidence in
three-phase networks. 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.
With the single-pole phase comparator SPPC, phase comparison is achieved by making
contact with both conductors one after the other.
Technical description:
Available for nominal voltages and nominal voltage ranges from 3 to 36 kV
Can be used with a rated frequency of 50 Hz
For reliable phase comparison, a rated frequency between 49.9 and 50.1 Hz is
required, with a maximum frequency drift of 10 mHz/s
Self-test feature
Automatic switch-off
Green, red and yellow LED display
Removable contact electrode top piece, as forked electrode
The single-pole phase comparator Type SPPC is designed to meet international
Standard IEC 61481.
Single-Pole Phase Comparator SPPC
The single-pole phase comparator SPPC is available for various nominal voltages and
voltage ranges. Depending on type, the phase comparator can also be used in rain or
snow.

Single-Pole Phase Comparator SPPC, Switchable
The single-pole phase comparator SPPC is available for various nominal voltages
and voltage ranges. Depending on type, the phase comparator can also be used in rain
or snow. This phase comparator can also be switched between three nominal voltage
ranges using the voltage range switching ring. This allows a larger system range to be
