Annotation of standard text IEC 62271-102-ed.2.0 :

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:

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