air-insulated switchgear (AIS) and gas-insulated switchgear (GIS) can be driven objectively by understanding the differences between the equipment. Today, the bulk of installed equipment is air-insulated switchgear. Yet gas-insulated equipment can provide advantages in certain applications. As we’ll see on the next page, one

THE first generation of gas-insulated switchgear (GIS) that Hitachi developed was 550 kV. Developed in 1978, this GIS used 4-break circuit breakers and all of its phases were of the separated-phase type. Later, circuit breakers were changed to the 2-break type. In 1989, the LIWV (lightning impulse withstand voltage) was lowered by using a high
