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.
\nThis second edition cancels and replaces the first edition published in 2001, Amendment 1:2011 and Amendment 2:2013. This edition constitutes a technical revision.
\nThis edition includes the following significant technical changes with respect to the previous edition:<\/p>\n

    \n
  1. new numbering according to IEC 17\/1025\/RQ to harmonize with ISO\/IEC Directives, Part 2, and IEEE Std. C37.100.1;<\/li>\n
  2. clause numbering has been aligned with IEC 62271-1:2017;<\/li>\n
  3. 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>\n
  4. 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>\n
  5. new rating values for bus-transfer current and bus-transfer voltage have been assigned;<\/li>\n
  6. new class of mechanical endurance for earthing switches has been added (M1);<\/li>\n
  7. subclause "Rated values of electrical endurance for earthing switches" is now called "Classification of earthing switches for short-circuit making capability";<\/li>\n
  8. new subclause with ratings for ice-coating has been added;<\/li>\n
  9. new subclause with classification of bus-charging switching capability has been added;<\/li>\n
  10. new withstand requirements for interlocking devices have been added;<\/li>\n
  11. the way to comply with the requirements of the isolating distance of disconnectors has been modified;<\/li>\n
  12. design and construction requirements for position-indicating devices have been modified, aligning the requirements for position indication and signalling;<\/li>\n
  13. the value of the operating force has been changed;<\/li>\n
  14. the test procedures and validation criteria have been revised and modified where necessary;<\/li>\n
  15. requirements for applied voltage during single-phase test on non-simultaneous closing earthing switches have been changed;<\/li>\n
  16. non-verifiable requirements have been deleted;<\/li>\n
  17. a new subclause has been added for testing mechanical interlocking devices;<\/li>\n
  18. the high- and low-temperature test is mandatory if the temperature limits for the service conditions of the apparatus (defined by the manufacturer) are above +40 \u00b0C or below -5 \u00b0C, and a more detailed testing procedure is given;<\/li>\n
  19. the testing procedure to verify the proper functioning of the position-indicating device allows a more practicable testing for every technology used;<\/li>\n
  20. a new Annex B has been added with title: "Current-switching capability required of disconnectors and earthing switches";<\/li>\n
  21. a new Annex C has been added with title: "Tolerances on test quantities for type tests";<\/li>\n
  22. a new Annex E has been added with title: "Extension of validity of type tests".<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
