Inhibition of Rejuvenation Liquid on Trees in XLPE Cables under Switching Impulse Voltages

open access: yesEnergies, 2019
In this paper, the inhibitory effect of preinjected rejuvenation liquid on trees in cross-linked polyethylene (XLPE) cables was investigated. Experimental samples were prepared by inserting needles into XLPE samples, and many equally-spaced holes existed

Space charge measurement as a diagnostic tool to monitor electrical ageing in polymeric materials

open access: yes, 2006
Space charge is a term used to describe the excessive charges in volume. Such excessive charges can be electrons, ions or mixture of both. In solid dielectrics space charge tends to build up at discontinuities, such as at the dielectric-electrode ...

Calibration of the Pulsed Electroacoustic Technique in the Presence of Trapped Charge

open access: yes, 2006
The influence of pulse voltage on the accuracy of charge density distribution in the pulsed electroacoustic technique (PEA) is discussed. It is shown that significant error can be introduced if a low dc voltage and high pulse voltage are used to ...
