The atmospheric relative humidity (RH) has a great impact on the partial discharge (PD) process which can damage the insulation in operating machines. This work investigates how the relative humidity would affect the PD activities in a metal-dielectric air gap on machine insulation, which consists of mica, epoxy resin and glass-fiber, with the application of periodic alternating trapezoidal voltage...
The decay of surface charges deposited on the dielectric material by the partial discharge (PD) activity has a great impact on the repetition of partial discharges. In this work, the effect of dielectric placed on the surface of ground electrode in a needle-plane configuration on the discharge activity was investigated, with the application of a periodic negative step voltage. The charge decay mechanisms...
