Extra-High-Voltage SF6 Gas-Insulated Switchgear· PDF fileExtra-High-Voltage SF6 Gas-Insulated Switchgear 1. Introduction Due to location criteria and toughened restrictions on transportation, it has become increasingly difficult over the past several years to secure sites for substa-tions. Consequently, the development of smaller-sized SF6 gas-insulated switchgear (GIS) has been eagerly awaited.
How Transformers Age | T&D World are designed with an expected life span of 30 years, though some in Japan have been in service for more than for 50 years. The need to replace transformers can be determined by evaluating individual conditions, but to plan a long-term transformer replacement program, it is necessary to determine the life expectancy of the asset.
