Overview This standard applies to all high-voltage enclosed indoor or outdoor@ and non-enclosed indoor or outdoor@ switches rated in excess of 1000 V. This includes such switch types as disconnecting@ selector@ horn-gap@ grounding@ etc.@ for manual or power operation. The following switch types are not covered by this standard: distribution-enclosed@ singlepole switches and distribution cutouts fitted with disconnecting blades; switches used in metal-enclosed gear covered by IEEE Std C37.20.2-1993@ IEEE Std C37.20.3-1987@ and IEEE Std C37.20.4-1996; and switches used in padmounted switchgear covered by IEEE Std C37.71-1984@ ANSI C37.72-1987@ and PC37.73 (Draft 8@ Feb. 95). NOTE ?? PC37.39@ Proposed Standard for Interrupter Switches@ is currently under development. Upon its approval and publication@ all references to interrupter switches in this standard will be superseded. This standard defines terms and words that uniquely apply to high-voltage switches and are not included in IEEE Std C37.100-1992. It also defines terms used for rating high-voltage switches and ratings that must be included on nameplates for high-voltage switches.
