High-voltage switchgear and controlgear - Part 102: Alternating current disconnectors and earthing switches
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:
new numbering according to IEC 17/1025/RQ to harmonize with ISO/IEC Directives, Part 2, and IEEE Std. C37.100.1;
clause numbering has been aligned with IEC 62271-1:2017;
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;
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;
new rating values for bus-transfer current and bus-transfer voltage have been assigned;
new class of mechanical endurance for earthing switches has been added (M1);
subclause "Rated values of electrical endurance for earthing switches" is now called "Classification of earthing switches for short-circuit making capability";
new subclause with ratings for ice-coating has been added;
new subclause with classification of bus-charging switching capability has been added;
new withstand requirements for interlocking devices have been added;
the way to comply with the requirements of the isolating distance of disconnectors has been modified;
design and construction requirements for position-indicating devices have been modified, aligning the requirements for position indication and signalling;
the value of the operating force has been changed;
the test procedures and validation criteria have been revised and modified where necessary;
requirements for applied voltage during single-phase test on non-simultaneous closing earthing switches have been changed;
non-verifiable requirements have been deleted;
a new subclause has been added for testing mechanical interlocking devices;
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;
the testing procedure to verify the proper functioning of the position-indicating device allows a more practicable testing for every technology used;
a new Annex B has been added with title: "Current-switching capability required of disconnectors and earthing switches";
a new Annex C has been added with title: "Tolerances on test quantities for type tests";
a new Annex E has been added with title: "Extension of validity of type tests".
Appareillage à haute tension - Partie 102: Sectionneurs et sectionneurs de terre à courant alternatif
L’IEC 62271-102:2018 s’applique aux sectionneurs et aux sectionneurs de terre à courant alternatif, conçus pour être installés à l’intérieur et à l’extérieur, pour des tensions nominales supérieures à 1 000 V et des fréquences de service inférieures ou égales à 60 Hz.

modification des exigences de conception et de construction des indicateurs de position, en alignant les exigences pour l’indication et la signalisation de position;
modification de la valeur de l’effort de manœuvre;
révision et modification si nécessaire des procédures d’essai et des critères de validation;
modification des exigences relatives à la tension appliquée lors des essais monophasés sur les sectionneurs de terre à fermeture non simultanée;
suppression des exigences non vérifiables;
ajout d’un nouveau paragraphe pour soumettre à l’essai les dispositifs de verrouillage mécanique;
réalisation obligatoire de l’essai aux températures haute et basse si les limites de température pour les conditions de service de l’appareil (définies par le constructeur) sont supérieures à 40 °C ou inférieures à -5 °C, et fourniture d’une procédure d’essai plus détaillée;
réalisation d’essai matériellement possible sur chacune des technologies utilisées, favorisée par la procédure d’essai de vérification du bon fonctionnement de l’indicateur de position;
ajout d’une nouvelle Annexe B intitulée: "Pouvoir d’établissement et de coupure de courant exigé des sectionneurs et des sectionneurs de terre";
ajout d’une nouvelle Annexe C intitulée: "Tolérances sur les grandeurs d’essai pour les essais de type"

Interpretation of 4.2.2 of IEC 62271-1:2017 regarding the altitude correction factor
Subclause 4.2.2 of IEC 62271-1:2017 contains two references for calculation of the required
insulation withstand level at altitudes higher than 1 000 m, IEC 60071-2:1996 and
IEC TR 62271-306. The two references are in conflict, as the altitude correction factor
according to IEC 60071-2:1996 starts at sea level and that of IEC TR 62271-306 starts at an
altitude of 1 000 m. This results in different altitude correction factors.
As already stated in 5.3 of IEC 62271-1:2017, the rated insulation levels refer to normal
service conditions. Altitudes up to 1 000 m above sea level are covered and need no altitude
correction.
For altitudes higher than 1 000 m the equation provided in 4.5.1.1 b) of
IEC TR 62271-306:2012 and in H.3.4 of IEC 60071-2:2018 shall be used, i.e.

k is the altitude correction factor;

Conservative values for the exponent m are provided in Table 4 of IEC TR 62271-306:2012.
