About This Item
Full Description
IEC 62271-102:2018 applies to alternating current disconnectors and earthing switches, designed for indoor and outdoor installations for nominal voltages above 1 000 V and for service frequencies up to and including 60 Hz. This second edition cancels and replaces the first edition published in 2001, Amendment 1:2011 and Amendment 2:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: <ol style="list-style-type:lower-alpha"> <li>new numbering according to IEC 17/1025/RQ to harmonize with ISO/IEC Directives, Part 2, and IEEE Std. C37.100.1;</li> <li>clause numbering has been aligned with IEC 62271-1:2017;</li> <li>the Scope has been extended to cover all indoor and outdoor installations. Consideration of switching devices having disconnecting and/or earthing switch functionalities, apart from other functions, are also covered by this document;</li> <li>ratings have been moved from Annexes B, C and E to Clause 5; the order of the subclauses now corresponds to the order of subclauses in Clause 7;</li> <li>new rating values for bus-transfer current and bus-transfer voltage have been assigned;</li> <li>new class of mechanical endurance for earthing switches has been added (M1);</li> <li>subclause "Rated values of electrical endurance for earthing switches" is now called "Classification of earthing switches for short-circuit making capability";</li> <li>new subclause with ratings for ice-coating has been added;</li> <li>new subclause with classification of bus-charging switching capability has been added;</li> <li>new withstand requirements for interlocking devices have been added;</li> <li>the way to comply with the requirements of the isolating distance of disconnectors has been modified;</li> <li>design and construction requirements for position-indicating devices have been modified, aligning the requirements for position indication and signalling;</ ...
