IEEE Draft Standard for Definitions for AC (52 kV and Below) and DC (3.2 kV and Below) Switchgear Assemblies

The terms and definitions in the standard are intended to encompass the products within the scope of ac (38kV and below for air insulated equipment, 52kV and below for gas insulated equipment) and dc (3.2 kV and below) power switchgear assemblies, including components for switching, interrupting, metering, protection, and regulating purposes as used primarily in connection with generation, transmission, distribution, and conversion of electric power.
