Abstract
A system for detecting loss of an electrical phase in a compressor system includes a compressor system component having a plurality of phase carrying legs; a sensor for measuring current communicated with one leg of the plurality of phase carrying legs; and a processor unit adapted to receive a signal from the sensor and determine whether loss of phase has occurred in any of the plurality of phase carrying legs.
