| Abstract: | In order to realize digitalization of partial discharge (PD) measurement, a set of digital PD measuring system is developed. The measuring system has higher pulse resolution and good linearity. It can be used to determine various characteristic parameters and spectrum charts of PD. In practical measurement, the system is convenient to use and its performance is reliable. Various quantitative results in different aspects obtained by using this digital measuring technique for PD characteristics determination can provide essential conditions for mechanism analysis and state assessment of electrical insulation degradation. |
