摘要：

In order to study the electromagnetic wave characteristics of multiple PD sources in the intermediate joint of XLPE cable, a 110 kV XLPE cable joint model is established. By constructing a good cable model, the cable and its intermediate joints are analyzed in time domain. The propagation characteristics of electromagnetic waves when partial discharge occurs, and the propagation characteristics are simulated to analyze the mutual influence of electromagnetic waves generated when multiple partial discharge sources propagate in different directions. The simulation results show that when multi-point partial discharge occurs, the measured electromagnetic wave waveform and amplitude have significant changes.
