Self-Adaptive Morphological Filter for Noise Reduction of Partial Discharge Signals
Partial Discharge assessment in the insulation of high voltage equipment is one of the most popular approaches for prevention of the insulation breakdown. In the procedure of thisassessment, noise reduction of partial discharge signals to get the original PD signal for accurate evaluation is inevitable. This denoising process shall be carried out such a way that the main features of the p...
متن کاملDetection of Partial Discharges in Power Transformers using UHF PD Measurements and Acoustic Measurements
For examination and diagnostics of the insulation quality of high voltage devices the measurement of partial discharge (PD) is accomplished. The conventional PD measurement according to IEC60270 is in some situations not sensitive enough because of the high interference level in field. The development of an unconventional measuring method using electromagnetic probes is presented. These probes ...
متن کاملAnalysis and Diagnosis of Partial Discharge of Power Capacitors Using Extension Neural Network Algorithm and Synchronous Detection Based Chaos Theory
Power capacitors are important equipment of the power systems that are being operated in high voltage levels at high temperatures for long periods. As time goes on, their insulation fracture rate increases, and partial discharge is the most important cause of their fracture. Therefore, fast and accurate methods have great importance to accurately diagnosis the partial discharge. Conventional me...
متن کاملEvaluating the Improvement of Partial Discharge Localization Accuracy Using Frequency Response Assurance Criterion
Partial Discharge (PD) is the most important source of insulation degradation in power transformers. In order to prevent catastrophic failures in transformers, PDs need to be located as soon as possible so that maintenance measures can be taken in time. Due to the structural complexity of windings, locating the PD source inside a transformer winding is not a simple task. In this paper, the effi...
متن کاملبررسی عملکرد پروب‌های UHF در آشکارسازی تخلیه جزئی در ترانسفورماتورهای فشار قوی
Recently, UHF partial discharge (PD) detection on power transformers attracts lots of attentions. For the transformers already installed in power network, the UHF signals can be captured only by UHF probes installed through oil drain valve. Although UHF probes are commercially produced, there are a lot of missing information on characteristics and features of these probes for PD detection. In t...
