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… read more 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) read less

This document provides standard requirements for interrupter switches, interrupters, or interrupting aids used on or attached to switches rated for high-voltage ac above 1000 V and used indoors, outdoors, or in enclosures for non-fault current interrupting for which an interrupting duty is assigned. This standard covers preferred ratings, construction, application, loading, installation, operation, and maintenance guidelines. This standard does not apply to load-break separable insulated connectors, circuit breakers, circuit switchers, metal-enclosed switchgear, pad-mounted switchgear, reclosers, sectionalizers or other switching devices that are covered by other IEEE standards.

This project will add new definitions and revise existing definitions to bring the document up to date. Altitude correction factors will be revised to reflect the recommendations of the Switchgear Committee "Common Clauses" working group. Standard C37.40b, definitions for Capacitor Fuses, will be incorporated into the new document.

This standard summarizes various design tests that shall be made on all types of high-voltage enclosed indoor or outdoor and non-enclosed indoor or outdoor air switches, and describes accepted methods used in making these tests. For tests on apparatus insulators, see ANSI C29.1-1988.1 High-voltage air switches in IEEE Std C37.20.2-1987, IEEE Std C37.20.3-1987, IEEE Std C37.71-1984, and ANSI C37.72-1987 are not covered by this standard.

This guide is intended to provide air switch users with a means for determining the magnitude of excitation as well as resistive and capacitive currents that may be successfully interrupted with horn-gap, vertical-break air switches in outdoor locations mounted in the normal horizontal-upright position and not equipped with interrupting aids. The minimum centerline-to-centerline phase spacing of each switch is based upon dimensions stated in ANSIC37.32-1972 [B1]1 , Table 5, Column 6. This guide assumes that the switches are applied to an effectively grounded wye system. A guide for ungrounded systems is being considered.

This standard applies to single- or multi-pole ac switches for rated maximum voltage above 1 kV to 38 kV for use in switching shunt capacitor banks (see the note in this clause). This standard covers the application of capacitive load switching wherein the capacitive loads are separated by sufficient inductance to limit the transient peak inrush current to the peak values shown in Table 2 and Table 3. Switches designed and built in accordance with this standard are rated for routine switching… read more of capacitive load currents only. NOTE--This standard is intended to be a comprehensive standard for all "specific duty" applications of switches in the area of switching shunt capacitor banks, but it is limited in scope up to and including 38 kV. However, subject to agreement between the user and manufacturer, it may be used as a specification guide for other rated voltages. read less
