The purpose of this manual is to assist the user in developing safe and eficient procedures for the installation, maintenance and operation of the equipment. For additional information, refer to NEMA Standards Publication PB2. Dive in to power up your knowledge! These guidelines govern the busbar processing and installation procedures. With the exception of SF6-to-air bushings terminals, all active portions of gas-insulated switchgear (GIS) are contained within grounded enclosures, which means that they are not susceptible to inadvertent contact. This makes gas-insulated switchgear intrinsically safe. In addition, numerous.
