_____________

INTRODUCTION
This amendment cancels and replaces IEC 61633.
The original edition of IEC 62271-101 (2006) makes extensive reference to
IEC 62271-100:2001. Since then, a new edition of IEC 62271-100 has been published (2008).
Within this amendment, references are made to IEC 62271-100:2008. Unless they are
explicitly mentioned in this amendment, all of the references in the original edition of
IEC 62271-101 (2006) still make reference to IEC 62271-100:2001. A second amendment to
IEC 62271-101, which will update all cross-references to the new IEC 62271-100:2008, is
under consideration.


Change "Tables I.1a through I.2d" to "Tables 15 through 22 of IEC 62271-100:2008" in the
whole document.

4.2.4 Other synthetic test methods
In the second paragraph, replace “IEC 61633” by “Annex O of IEC 62271-100:2008”.

6 Specific requirements for synthetic tests for making and breaking
performance related to the requirements of 6.102 through 6.111 of
IEC 62271-100
Add the following text at the end on the first paragraph:
Annex O of IEC 62271-100:2008 gives guidelines for the testing of metal-enclosed and dead
tank circuit breakers.

Add the following subclause:
6.102.4.2 Unit testing
For the application of the synthetic test methods to one or more units of a circuit breaker, the
requirements of 6.102.4.2 of IEC 62271-100:2008 are applicable. In the case of metal-
enclosed or dead tank circuit-breakers, Annex N gives details of some typical test circuits and
Annex O of IEC 62271-100:2008 outlines appropriate testing guidelines.


6.111 Capacitive current switching tests
Add the following text:
For metal-enclosed and dead tank circuit-breakers, typical test circuits are given in Annex N
and additional guidelines are given in Annex O of IEC 62271-100:2008.

Add the following new Annex N:

Annex N

(informative)




Typical test circuits for metal-enclosed and dead tank circuit breakers




This annex outlines some typical synthetic test circuits for type testing relevant to short-circuit

making, breaking and switching performance of metal enclosed and dead tank circuit-

breakers. Other methods are not excluded provided that they supply the correct stresses to
the pole terminals, between the phases and between the terminals and the enclosure of the
circuit-breaker.
Many circuits are possible with different features. Some examples are given in Figures N.1
through N.9 as follows:
– terminal fault tests on one or more units of metal-enclosed or dead tank circuit-breakers
(Figures N.1 to N.4);
– capacitive current switching tests (Figures N.5 to N.7);
– out-of-phase switching tests (Figure N.8);
– full pole terminal fault tests with voltage applied to both terminals and the metal enclosure
(Figure N.9).
