Abstract:
An example fault detection circuit includes: a positive sequence voltage calculator to calculate a positive sequence voltage value for a three-phase motor; a positive sequence current calculator to calculate a positive sequence current value for the three-phase motor; an interpolator to calculate an expected negative sequence voltage value based on the positive sequence voltage value, the positive sequence current value, and measured characteristics of the three-phase motor; a negative sequence voltage calculator to calculate a measured negative sequence voltage value for the three-phase motor; and a fault detector to detect that a winding fault exists in the three-phase motor when a difference between the expected negative sequence voltage value and the measured negative sequence voltage value satisfies a threshold.

Claim (Index 7):
The fault detection circuit of  claim 1 , wherein the fault detector is to: enter a transient state when first measured changes in a set of positive sequence voltage values are greater than a first threshold or when second measured changes in a set of positive sequence current values are greater than a second threshold; detect that the winding fault exists only while the first measured changes in the set of positive sequence voltage values are less than the first threshold and the second measured changes in the set of positive sequence current values are less than the second threshold; and not detect whether winding faults exist while in the transient state.
