Sažetak
When undertaking a survey into the reliability of electrical equipment it is important to consider how utilities/manufacturers/universities apply and benefit from the calculated availability, failure rates and other parameters in the survey. A summary of survey data applications and benefit is provided. Electrical networks worldwide have an increasingly aged population of electrical equipment. This survey helps the owners and operators of these networks to understand the impact of aged equipment (SF6 breakers, instrument transformers, GIS, disconnections and earthing switches) on network performance and helps mitigate the effects through proper operation, effective maintenance, monitoring, asset refurbishment and asset replacement. For new and expanding networks, the survey will help to optimise design and help define operation, maintenance and monitoring of the assets to achieve the desired level of network performance. Additionally the survey will aid in adopting a more statistical approach to asset management including maintenance and replacement. Two case studies are presented, one for network performance and the other for asset (equipment) performance. Reliability data from the survey will have numerous uses, both when looking at network and asset (equipment) performance. This data is becoming more important as many electrical networks have ageing assets and many electrical networks are facing increased development.
