Fourth CIGRE international reliability survey on equipment operated in 2014-2017
The reliability of substation equipment in power systems is a major concern, particularly for transmission and distribution system operators and asset owners. A major failure of substation equipment can result in significant system outages with the associated power restoration efforts as well as possible safety implications. There are also financial implications in case of poor reliability. In addition to the costs of system outage and restoration, poor reliability will contribute to higher system operation and maintenance costs for the operators and, ultimately, their customers.
