IEEE C37.30.1-2011

This standard covers preferred ratings; construction and testing requirements; and application, loading, installation, operation, and maintenance guidelines for all high-voltage enclosed and non-enclosed, indoor and outdoor air switches rated in excess of 1000 V. This includes such switch types as disconnect, horn-gap, fault-initiation, and ground for manual or power operation. The following switch types are not covered by this standard: interrupter switches, distribution cutouts fitted with disconnecting blades, and switches used in metal-enclosed and pad-mounted switchgear. This standard also does not apply to load-break separable insulated connectors, circuit breakers, circuit switchers, or reclosers.
The purpose of this standard is to provide a basic standard for air switches.
New IEEE Standard – Inactive-Reserved. Required ratings, construction requirements, design test requirements, applications, and suggested practices for all high-voltage enclosed indoor and outdoor and non-enclosed indoor and outdoor switches rated above 1000 V are specified. This includes ratings and requirements for such switches as disconnecting, selector, horn-gap, and grounding for manual and power operation, except for interrupter switches, distribution-enclosed single-pole air switches, and distribution cutouts fitted with disconnecting blades.
