The test code has been patterned after IEC Publication 129, Specifications for Alternating Current Disconnectors (Isolators) and Earthing Switches, paragraph 48. The following specific comments noted are to assist in the evaluation of each section of the supplement stated below: 4.3 It is necessary to motor operate at minimum and maxium control voltage (as in IEC Publication 129) because operation at other than rated control voltage may produce significantly different forces and stresses from those produced during norma! voltage operatian. 4.4 IEC Publication 129 allows lubrication during the test, These proposed revisions do not. 5.3 Final judgment for acceptable completion of the mechanical nperations test (if there is any concern about contact pressure loss, voltage drop increase, or resistance increase through mechanical wear) requires satisfactory completion of a temperature rise or short-time current test. 517 $aANSI/IEEE C37.34d-1984: IEEE Standard Test Code for High-Voltage Air Switches 606 $aElectric switchgear$xStandards 606 $aElectric switchgear$xTesting 606 $aHigh voltages 615 0$aElectric switchgear$xStandards. 615 0$aElectric switchgear$xTesting. 615 0$aHigh voltages. 676 $a621.3 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910135779003321 996 $aANSI$92072434 997 $aUNINA
