High-voltage switchgear and controlgear - Part 103: Alternating current switches for rated voltages above 1 kV up to and including 52 kV
This edition includes the following significant technical changes with respect to the previous edition:
- this document has been aligned with IEC 62271-1:2017 and IEC 62271-102:2018;
- clarifications regarding the behaviour of the switch during breaking tests regarding current interruption and restrikes have been added;
- conditions of the switch after making and breaking tests have been clarified;
- a new informative Annex B intended to provide guidance for the calculation of Ief1 and Ief2 has been added;
- new rules for the combination of 50 Hz and 60 Hz switching tests have been defined and a new table (Table 7) has been added;
- tests with specified TRV have been modified to be in accordance with the practice described in IEC 62271-100;
- the behaviour of the switch during breaking tests has been clarified and boundaries for restrike allowance have been defined;
- explanations for short-circuit making tests have been added;
- vacuum integrity check after mechanical operations has been defined;
- all test voltages for single-phase capacitive testing have been grouped under 220.127.116.11.2 and have been confirmed by simulation and calculation.
