Abstract
The present invention relates to a system and method for the monitoring and detection of insulation degradation in electric systems. The system comprises a controller for an electric motor (), including input circuitry () for connecting the controller to a power supply (), power conversion circuitry () for providing a power output for the electric motor (), and sensing circuitry () for monitoring a current inside the controller that is representative of a return leakage current from the electric motor to the motor controller. A condition of the insulation may be determined based on the monitored current.
