Partial discharge detection under DC is an appropriate method for insulation condition estimation. This paper presented a DCPD measurement and analysis system. System, characterized by high signal to noise ratio and strong ability for interference suppression, was composed with narrowband RLC balanced detection circuit, gain-stable amplifier and band-pass filter. Through trigger acquisition, DCPD signal was transferred to the computer and data were processed based on~t analysis method in order to reflect characteristic parameters of PD signal by spectrum and fingerprint. Through the calibration by standard pulse generator, sensitivity of whole system reached 2pC which is enough to detect PD current in storage capacitor. Based on this measurement and analysis system, measurement for high-voltage storage capacitor with typical defects would be conducted and the results effectively reflected relationship of PD parameters. Therefore, the establishment of this system settled a good basis for defect types recognition and aging degree estimation of capacitors.

“…Most of the research was done by Fromm [16][17][18], Morshuis et al [19] and Gulski et al [20]. Fromm has built a model with parameters including discharge magnitude q i , time of discharge interval t i , and instantaneous voltage across the test object, which describes the stochastic discharge process at dc voltage.…”

Abstract-To remotely detect corona discharge from High-Voltage Direct Current (HVDC) transmission lines, a detecting system combining detecting platform and data progressing system is designed. Detecting platform is developed resorting to the principle of differential noise reduction, which can fulfill narrow-band detection breaking away interference from broadcasting and easily catch the electrostatic discharge signal. To get rid of interference from spark discharge, a data progressing system containing feature extractions, clustering and recognition technologies is developed. Clustering is realized by extracting five discharge features, including peak factor, form factor, skewness, kurtosis and mean square error. The unsupervised clustering Fuzzy C-Means (FCM) method is used to achieve fast separation for electrostatic discharges and provide training set for pattern recognition. Pattern recognition resorts to Support Vector Machine (SVM) method. For comparison, Back Propagation (BP) and Learning Vector Quantization (LVQ) approaches are taken to test the recognition ability. The results show that SVM recognizer with a recognition rate of 97.5% achieves higher performance than BP and LVQ methods. It can be concluded that the detecting system can be an interesting alternative for electrostatic discharge detection.
