Abstract Establishment of condition based maintenance for hydrogenerator is very important for monitoring the insulation of stator windings. The partial discharge (PD) testing is a promising method of stator winding insulation of hydrogenerator conditions monitoring. Therefore, the on-Iine PD testing has been used to provide useful information to diagnose and monitor the integrity of stator winding insulation of many hydrogenerators. In the paper, we described the examination of PD characteristics of on-line two hydrogenerator stator windings by using acoustic emission detection technique, and we considered the influence of the operation environments such as coil temperature, humidity and stopping time.
