PD measurement is a worldwide-accepted method for insulation diagnosis and a required part of the acceptance testing for many HV assets. To facilitate PD measurements different
techniques/methods have been developed and they are in use for laboratory and on-site applications. All

Performing on-site non-destructive testing and diagnosis of HV power cables is becoming an important issue to determine the actual condition of the cable systems and to determine the future performances. Therefore in this contribution based on field application of on-site testing

The aim of this article is to investigate the extent of space charge accumulation due to a temperature gradient in comparison with other charge-supply mechanisms, particularly injection from the electrodes. For this purpose, space-charge measurements were carried out on HVDC cabl

The electric field distribution of cable insulation systems under HVDC can be affected significantly at interfaces due to space charge build-up. In this article, the second part of a three-article series, face and space charge accumulation are analyzed first in terms of macroscop

This paper deals with the analysis of the effect of temperature gradient applied to polymeric cables on space charge accumulation inside insulation bulk. In particular, experimental measurements on HVDC cable models showed that space charge due to temperature gradient is generall
