A 10kV cross-linked polyethylene (XLPE) cable joint simulation model was established, in which the electromagnetic wave resulted from partial discharge (PD) was simulated by Finite Integration Technique (FIT). Factors influencing the electric field intensity and energy loss of UHF signals were analyzed. The simulation results indicate that quasi-TEM is the main propagation mode of EM wave, UHF signal intensity is related with the detection distance and the original PD pulse waveform. Streszczenie. Zbadano polączenie 10 kV kabli z izolacją polietylenową. Moze tam powatwac fala elektromagnetyczna jako rezultat wyladowania niezupelnego. Przeanalizowano natezenie pola elektrycznego i straty energii. Stwierdzono, ze quasi-TEM (linia dluga) jest glownym sposobem prppagacji flai elektromagnetycznej.
