Requirements for AC High-Voltage Air Switches Rated Above 1000 V
|Publication Date:||7 December 2011|
This standard covers preferred ratings; construction and testing requirements; and application, loading, installation, operation, and maintenance guidelines for all high-voltage enclosed and nonenclosed, indoor and outdoor air switches rated in excess of 1000 V. This includes such switch types as disconnect, horngap, 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.
