Abstract
The on-line monitoring of partial discharge on generators is more and more widely used to estimate the insulation condition of generator stator windings. In this paper a new detector for on-line monitoring of partial discharges of generators was introduced. The measurement of partial discharges was carried out on some generator model bars in a laboratory using the new detector. Features of different types of PD were analyzed using the spectrums of Hq(/spl phi/), Hn(/spl phi/) and Hn(q). Some primary results from field test are reported for a detector installed on a turbine generator in a power plant located in Shanxi Province of China.
