要約(日本語): As mechanical vibration usually exists in HV motors and generators, its influence on the partial discharge (PD) needs to be studied so as to improve the reliability of on-line PD monitoring method. In this report, the mechanical vibration frequency was synchronized to the power frequency and the effects of vibration phase and frequency were investigated. Because the length of the discharge gap changed with the vibration, obvious variation in the slot-PD patterns was observed at different vibration phase and frequency. Moreover, the PD patterns in the cases with unsynchronized vibration frequency or the violent collision between the coil and the ground electrode were also observed.
