minimum clearing time
Replace the entire term, definition, note and source as follows:
3.17
(void)
Add, after the definition 3.18, a new term and definition as follows:
3.19
intermediate asymmetry
level of asymmetry in the other two phases having a reduced (intermediate) level of
asymmetry when in a three-phase system the short-circuit current is initiated simultaneously
in all phases and maximum asymmetry is obtained in one of the phases
4.1.2 High-current interval
Replace the entire subclause by the following:
The tolerance on the amplitude and the power frequency of the prospective breaking current
is given in 6.103.2 and 6.104.3 of IEC 62271-100:2008. Therefore, the following conditions
concerning the actual current through the test circuit-breaker shall be met:
– for symmetrical testing the current amplitude and final loop duration shall not be less than
90 % of the required values based on the current of the test-duty considered;
– for SLF test-duties and T100s and T100a when tested with ITRV, the product of the
current amplitude and the duration of the final loop shall not be less than 95 % of the
required values based on the current of the test-duty considered;
– for asymmetrical testing, both the current amplitude and final loop duration shall be
between 90 % and 110 % of the required values, based on the current of the test-duty
considered and time constant (see Tables L.12 to L.17).
In rare cases, where the applied voltage from the high current source is of the same
magnitude as the required test voltage in a direct test circuit, a higher deviation of the last
current loop is accepted provided that the prospective current loop with the auxiliary circuit-
breaker arcing is within the specified tolerances.
4.1.4 High-voltage interval
Replace the first sentence of the first hyphen by the following:
The initial value of the power-frequency recovery voltage, excluding the transient oscillations,
shall not be less than the equivalent initial value of the power-frequency recovery voltage
specified in 6.104.7 of IEC 62271-100:2008 which, for a test with symmetrical current, starts
with a minimum peak value of 0,95×k ×U √(2/3).

4.2.1 Current injection methods
Replace, in the first sentence, "(see Annex B)" by "(see IEC 62271-306)".
Add, after the second indent, the following new sentences:
Current injection method is mandatory for:
– short-line fault test duties;

– 4 – IEC 62271-101:2012/AMD1:2017

– T100s and T100a when tested with ITRV.
The time during which the arc is fed only by the injected current shall be treated as part of the
length of the final current loop.
Replace the paragraph below the second hyphen by the following:
If any device with breaking capability interrupts the current through the test circuit-breaker at
the same time as the test circuit-breaker, the method is not a valid current injection method.
Replace, in item c), "(see Annex B)" by "(see IEC 62271-306)".
4.2.2 Voltage injection method
Replace, in the first sentence, "(see also Annex C)" by "(see IEC 62271-306)".
Delete the sentence below the third hyphen of the first list.
4.2.3 Duplicate circuit method (transformer or Skeats circuit)
Replace, in the first sentence, "(see also Annex D)" by "(see IEC 62271-306)".
Delete the penultimate paragraph.
Replace, in the last paragraph, "See Annex D" by "See IEC 62271-306".
4.2.4 Other synthetic test methods
Remove the last two paragraphs.

and T100s, k = 1,3
pp
Replace "98" by "97" (3 instances).
5.2.2 Test circuit
Replace the second sentence of the first paragraph by the following:
Examples of circuits showing voltage and current wave shapes are given in Figures 5 and 6
for single-phase and Figure 7 for three-phase.
6 Specific requirements for synthetic tests for making and breaking
performance related to the requirements of 6.102 through 6.111 of
IEC 62271-100:2008
Replace the existing title by the following new title:

Add, before the existing text of this clause, the following new title:
6.1 General
Replace the second paragraph by the following new paragraphs and new table:

Requirements concerning testing of metal enclosed and dead tank circuit-breakers are given
in Annex N.
General requirements for circuit-breakers with opening resistors are given in Annex R of
IEC 62271-100:2008/AMD1:2012. A method available for testing circuit-breakers having
opening resistors is reported in Annex F.
The abbreviations given in Table 6 are used to specify the operations to be performed.
Table 6 – Abbreviations used for operation during synthetic tests

voltage specified in 6.104.1 of IEC 62271-100:2008

DEF Double-earth fault test as defined in 6.108 of IEC 62271-100:2008/AMD2:2017
NOTE Due to the characteristics of synthetic testing it may be difficult to comply with the specified time intervals
of the rated operating sequence. See 6.105.1 of IEC 62271-100:2008/AMD1:2008.

In order to comply with all test requirements, it may be necessary to make more operations
than specified in the normal test-duty. In such cases the circuit-breaker may be reconditioned
and the test duty repeated.
