15、is publication is one of a series of seven standards (IEEE Std C37.30-1992 through IEEE C37.37-1979) on high-voltage air switches as follows:IEEE Std C37.30-1992, IEEE Standard Requirements for High-Voltage Air Switches.ANSI C37.32/D6/2-95, Schedules of Preferred Ratings, Construction Guidelines and

18、ches (ANSI).IEEE Std C37.37-1979 (Reaff 1993), IEEE Standard Loading Guide for AC High-Voltage Air Switches (in excess of1000 volts) (ANSI).This standard includes previously approved supplements that cover tests for ice breaking ability, mechanicaloperations, mechanical terminal loads, switching imp

19、ulse, limits of corona and radio influence voltage as well astemperature limits for air switches.This standard establishes a definition for corona, develops the concept of corona-free voltage, establishes therequirements for corona-free voltage, and the criteria for acceptance. The corona-free volta

20、ge is specified to be 1.10times the line-to-neutral voltage equivalent of rated maximum voltage. Only visible corona is defined because thissatisfies the majority of user requirements. Actual tests performed show satisfactory radio influence voltage (RIV)levels after the extinction of visible corona

21、 over the extremities of the device.In the past, switches determined to be corona-free by the human eye accustomed to a darkened area have not been asource of radio or television interference. This standard, however, allows an alternate photographic corona test methodwhere necessary.Switch-mounting

22、heights and proximity to other objects during tests have been limited so that they are representativeof unfavorable operating conditions that could occur in a service location.Tests require the switches to be free of visible corona at the corona extinction voltage because this voltage is lower thant

23、he corona starting voltage.The specified ice tests are coordinated with IEC 129 (1984), which are intended for severe conditions of ice formation.The ice tests describe a method for natural environment (outdoor) testing. They establish criteria for acceptance, whichare necessary to demonstrate compl

24、iance with the standard. Specific requirements have been added for manually-operated, power-operated, and fault-initiating switches.The purpose of the mechanical operations test is to demonstrate the ability of a completely assembled switch to operatesatisfactorily during its operating life expectan

25、cy.ivSubclause 4.3 on the power frequency and lightning impulse open gap withstand voltage test has been revised to allowa bias test as an alternate to the standard test for switches rated 362 kV and above. Also, 4.4 on switching-impulse testsof extra-high voltage switches has been rewritten to util

26、ize the test procedures contained in IEEE Std 4-1978 andIEC129 (1984). The up-and-down method is used to establish phase-to-ground rated withstand voltage of the switchand the 3 9 test is used to verify the open gap withstand voltage. See annex A for background information.The material was updated t

27、o conform with presently accepted standard conditions and switching-impulse wave shape.Also, the procedure for determining the maximum dispersion has been deleted, and a specific standard deviation isdesignated in case adequate test data is not available to determine the actual value.To harmonize wi

28、th IEC 129 (1984), the terms peak withstand current (formerly momentary current) and short-time(symmetrical) withstand current (formerly 3-s current) have been introduced. Also, a three-phase test is permitted onswitches rated 48.3 kV and below to verify the peak withstand current rating of the swit
