Abstract
To suppress the stochastic pulse interference in XLPE Cables, this paper uses equivalent time-frequency method to extract pulse feature values, adaptive fuzzy clustering to classify pulses, phase concentration as an index to distinguish PD and stochastic pulses. Analysis results of on-site data show that this method can effectively suppress stochastic pulse interference in the PD signal, providing a useful theoretical and practical basis to assess the state of XLPE cable insulation.
