What impact does partial discharge have on the insulation life of a cable?
Partial Discharge (PD) is the leading driver of irreversible dielectric degradation and premature failure in medium- and high-voltage cable insulation systems. According to global power utility statistics, over 80% of insulation breakdowns in Cross-linked Polyethylene (XLPE) and PVC cables are preceded by ongoing PD activity. The impact of PD on insulation life is non-linear, characterized […]
