Substation monitoring systems for asset management, development and analysis of results

New competitive electrical markets impose improvement in service performance. Therefore, it has become of upmost importance the early detection of incipient faults or defects in all involved equipment. Maintenance costs can be reduced by using monitoring systems to change from periodic maintenance practices to condition based maintenance. Also, manufacturers find in remote monitoring systems a good possibility for the analysis of the behaviour of equipment that could never be done in the past. Therefore, they can use this information as a differential in present demanding markets increasing warranty periods. During the last three years, our company has been doing research and development of monitoring systems. With all the gathered information, it is possible to assess the equipment condition in a wiser way.
