Abstract
A method for monitoring a compressor includes measuring a power factor of a motor of a compressor. The method includes selectively detecting an occurrence of a fault event of an electrical grid based on the power factor. The method includes, in response to detecting that the fault event has occurred, switching the compressor from a first state to a second state. The compressor consumes less power in the second state than in the first state. The method includes identifying an apparent conclusion of the fault event. The method includes, in response to the apparent conclusion of the fault event, waiting for a first delay period before switching the motor of the compressor back to the first state.
