Electromagnetic Waves Propagation and Detection in Shielded Dielectric Power Cables

Abstract

Partial discharge occurs a lot in shielded dielectric power cables. Partial discharge pulses are high-frequency electromagnetic waves that propagate in the shielded dielectric power cables. This chapter will study partial discharge propagation and detection in shielded dielectric power cables.

Modelling and experimental validation of EM wave propagation due to PDs in XLPE cables

“…A detailed study on the propagation of EM waves is necessary for detection and localisation of PD sources by a proper interpretation of the measured signals. The occurrence of PDs in the insulation radiates EM waves inside and outside the cable geometry [28,29]. The conduction and displacement of current components in the PD current are the major sources of EM waves in the insulation of power equipment.…”
