Recently, many equipments in power facilities, especially hydrogenerators installed at high-growth period of the economy will pass over about 40 years, and is seeing an updating term. However, under the recent economically severe condition of social environment, there is a strong demand to use these equipments to a life limit by understanding about their performance. Furthermore, in order to raise the utilization rates of the production facilities, the diagnosis at an on-line condition is also desired. In order to meet the requests, it is required to understand as correctly as possible the performance of these equipments under the on-line condition.In order to build up the insulation deterioration diagnosis of the on-line hydrogenerator stator windings, we measured the AE signal and the leakage current of neutral point grounding line attended with partial discharge for two hydrogenerators using with the hybrid insulation deterioration diagnosis device. We put in the device at the two hydrogenerators, and we measured the AE signal and the leakage current of neutral point grounding line for a long term, respectively.
