Patent number: 9257922Abstract: Current imbalance may be detected in a 3-phase power system by monitoring current output between two points of a phase signal provided along wire pairs from an inverter to a motor. In some embodiments, each wire of a wire pair leading to the motor from the inverter may be provided with a line current sensor. A comparison of current output from each wire in the wire pair may be performed to determine if a current imbalance is present. In some embodiments, a phase current sensor may be coupled to a phase input of the inverter. Failures in the 3-phase system may be detected by measuring the output from each phase current sensor for imbalanced distribution of power output. In some embodiments, the output from the phase current sensors may be compared to an output of a line current sensor along the same phase for current imbalances or harness failures.Type: GrantFiled: March 15, 2013Date of Patent: February 9, 2016Assignee: HONEYWELL INTERNATIONAL INC.Inventors: William Warr, Evgeni Ganev, Chiyuan Chiang
