Partial discharge measurement with pulse height analyzer

Partial discharge measurements and data processing are very significant factors in the study of partial discharge phenomena and the development of diagnostic techniques for insulation used in electrical machines. Partial discharges have many time-varying parameters which can be measured and analysed. In order to introduce laboratory automation in the study on partial discharge phenomena, a new system using commercial multi-channel analyzer and minicomputer has been developed. Several experimental results show it could become a more useful system for diagnostics provided more essential data processing programs are developed.
