摘要： A signal obtained from the drive input of a motor or an insulated winding is applied to a sensor that strongly rejects high frequency drive signal components yet passes discharge signal components. This allows discharge signal components to be detected in the presence of harmonics of the drive signal. The voltage of the drive signal may be varied so that the lowest drive signal voltage producing a discharge event may be determined. That voltage is the motor or winding's corona inception voltage.

摘要： A radio frequency (RF) or other form of detector detects discharges of an insulated system which can occur when electrical insulation becomes wet, for subsequent analysis and decision processes. Additionally, for RF detection, a frequency selector can be used to select a “quiet” region of the discharge spectrum before demodulation and further analysis and decision. Finally, redundant sets of such filters avoid the need to continuously reconfigure the detection system.
