Abstract :
Due to the competitive environment of the power generation industry, new approaches to condition assessment and maintenance of rotating electrical machines are being explored. Analysis results from partial discharge measurements have proven to be a key tool in predictive maintenance strategies. In this paper, common methods used by ABB for conducting partial discharge measurements are discussed. Special respect is given to online monitoring and the generation of alarms. A key to providing better alarm generation is described. Also, the actions that will be taken after an automatic alarm has been generated by the partial discharge measurement equipment are considered
