Partial Discharge Measurement Systems
Partial Discharges (PD) are evidences of a degrading insulation capacity, which will lead to cost-intensive repairs and can predictively lead to an electrical breakdown of the HV apparatus. Partial discharges are mainly caused by natural circumstances or by accelerated ageing of the HV insulation, but also manufacturing or installation failures can lead to harmful partial discharges. Therefore, the goal of partial discharge measurements is to detect the partial discharges in an early stage and to evaluate them in a proper way. Periodic, as well as permanent, partial discharge measurements have become one of the main criteria in assessing the quality and condition of HV equipment such as transformers, generators, switchgear and cable systems.
