Defects in ceramic insulators like broken, cracked and punctured discs give rise to the initiation of partial discharge (PD) activities within the samples which has a detrimental effect on the insulator life. Hence it is important for the utilities to identify such defective samples as early as possible so that appropriate replacement strategies can be devised. The work presented in this paper involves...
North American utilities are increasingly concerned with their ageing ceramic insulator assets as they are either fast approaching their expected end of life or have already exceeded them. Defects like broken, cracked and punctured discs are some of the most adverse problems that the utilities encounter. These defects give rise to the initiation of partial discharge (PD) activities within the samples...
The presence of insulation defects results in the initiation of partial discharge (PD) activities. As insulation failure and hence a failure of power equipment can occur due to the cumulative adverse effects of partial discharges, it is important to detect PD activities at early stages. The current techniques used in PD off-line analyses are not suitable for detecting defected insulators in the field...
