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 $a996279879003316 996 $aANSI$92072434 997 $aUNISA LEADER 02157nam 2200469z- 450 001 9910557742503321 005 20211118 035 $a(CKB)5400000000045917 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/73212 035 $a(oapen)doab73212 035 $a(EXLCZ)995400000000045917 100 $a20202111d2019 |y 0 101 0 $aeng 135 $aurmn|---annan 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aEcology and Evolution of Plants under Domestication in the Neotropics 210 $cFrontiers Media SA$d2019 215 $a1 online resource (284 p.) 311 08$a2-88963-047-1 330 $aThis eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!
