A structured life extension program can help utilities make equipment replacement/refurbishment decisions that ensure safe, reliable, cost-effective operation of transmission substation equipment. These guidelines support current utility practices and industry standards while forming a basis for establishing a maintenance and condition assessment program. These guidelines incorporate the experience of utility, consulting, and equipment engineers to offer a cross section of utility practices for extending the life of substation equipment. Equipment covered in the guidelines include power transformers, circuit breakers switches, relay and control systems, bus and structures, dc systems, grounding systems, surge arresters, control cables, and bushings. The guidelines provide generic approaches to maintenance of substation equipment and systems, condition assessment of major equipment, and decision making regarding refurbishment/replacement options. Incorporated in the guidelines are discussions of such areas as the type of maintenance applied to subject equipment, routine maintenance and inspection procedures, common tests performed as part of a condition assessment program reasons for tests and use of test results, factors to be considered when deciding on replacement/refurbishment, and costs associated with the process.
