Abstract :
In today´s energy market, operators want to minimize the costs for maintenance and outages. Condition-based maintenance techniques using diagnostics and or monitoring systems are a prequisit in power grids nowadays. At times where the need for such systems is increasing, the time and knowledge available for analysis and interpretation is decreasing. Therefore, STRI, LDIC, VB Kraft and VB Elnat have decided to develop an on-line web-based PD monitoring system to monitor one of the generators installed in a hydropower plant owned by VB Kraft. The aim of this project is: a) to get service experience with such a system b) to develop a system that is easy to use and gives the user the information that is needed in a way that is understandable for them at times that they need it. In this paper the complete system including, measuring system, generator, transmission system and website together with the so-far obtained service experiences are presented.
