DIMENSIONS
DESCRIPTION
The
Model 2522
continuously monitors 3-phase power
lines for abnormal conditions. When properly adjusted, the
Model 2522 will detect phase loss on a loaded motor even
when regenerated voltage is present.
This unit consists of a solid-state voltage and phase-angle
sensing circuit, driving an electromechanical relay with
DPDT contacts. When correct voltage and phase rotation
are applied, the internal relay will energize. A fault
condition will de-energize the relay. When the fault is
corrected the Model 2522 will reset.
Both automatic and manual reset versions are available.
The Model 2522 does not require a neutral connection, and
can be used with Wye or Delta systems. Adjustment
ranges are sufficiently wide to allow for proper adjustment
to existing conditions. A failure indicator is provided to aid
in adjustment and system troubleshooting.
