Abstract:
1. A system comprising: at least one capacitor; a first resistance coupled to the at least one capacitor; a plurality of electronic switching devices coupled to at least the first resistance and the at least one capacitor, wherein the plurality of electronic switching devices are configured to couple the at least one capacitor to a power source to charge the at least one capacitor during a first time interval, the plurality of electronic switching devices including a first electronic switching device and at least one second electronic switching device, the first electronic switching device being configured to close to couple the at least one capacitor to a second resistance associated with a winding insulation while the at least one second electronic switching device is open to allow the at least one capacitor to discharge during a second time interval after the first time interval, the plurality of electronic switching devices are configured to control the flow of current from a generator to a motor; and the second resistance corresponds to a resistance of a winding insulation associated with the motor or the generator; a voltage measuring device configured to detect a change in voltage at a terminal of the at least one capacitor in response to the closing of the first electronic switching device during the second time interval; and a computing system configured to determine a condition of the winding insulation based on the detection.
