Description
Summary:A competitive national electricity market increases the incentive to reduce maintenance costs and outages on the transmission network. There is a particular need to reduce the frequency and duration of forced outages caused by equipment defects. Effective condition monitoring provides a powerful tool to achieve these objectives. The emergence of new technologies, coupled with a paradigm shift in asset management from time-based to condition-based maintenance, has led to condition-monitoring devices becoming commonplace in many modern substations. TransGrid set out to develop an extensive condition-monitoring system in response to the asset-management drivers of reliability, availability and cost. The utility established an initial trial at the new Dumaresq 332-kV Switching Station. TransGrid developed a broader philosophy for real-time condition monitoring and implemented a real-time monitoring system that incorporates several substations across the high-voltage network. The presence of an online monitoring system does not replace the careful thought given to which parameters to monitor, but it makes the acquisition and manipulation of data substantially easier.
