Partial discharge (PD) measurement system based on high frequency current transducer (HFCT) provides a convenient and cost-effective means for online insulation condition monitoring of transformers. However, it is a difficult task to extract PD signals from the measured signals overwhelmed by noise, which consequently leads to ambiguities in the condition assessment of transformers. This paper develops...
Partial discharge (PD) monitoring can reveal various types of insulation defects and provide an effective means for condition assessment of high voltage (HV) equipment. One of the challenging tasks of PD monitoring is to effectively extract PD signals from acquired signals, which are susceptible to extensive noise. The extracted PD signals can then be further processed for identifying the insulation...
