1.2 Normative references
Add the following new references to the existing list:

3.4.101
disconnector
Replace the content of Notes 1 and 2 as follows:

NOTE 1 "Negligible current" implies currents such as the capacitive currents of bushings, busbars, connections,
very short lengths of cable, currents of permanently connected grading impedances of circuit-breakers and currents
of voltage transformers and dividers (see also IEC 62271-305). For rated voltages of 420 kV and below, a current
not exceeding 0,5 A is a negligible current for the purpose of this definition; for rated voltage above 420 kV and
currents exceeding 0,5 A, the manufacturer should be consulted. "No significant change in voltage" refers to such
applications as the by-passing of induction voltage regulators or circuit-breakers and bus transfer.
NOTE 2 For a disconnector having a rated voltage of 52 kV and above, a rated ability of bus transfer current
switching may be assigned.
3.4.105
earthing switch
Replace the existing text by the following:
IEV 441-14-11 is applicable with the following additional notes
NOTE 101 An earthing switch having a rated voltage of 52 kV and above may have a rating for switching and
carrying induced currents.
62271-102 Amend.1 © IEC:2011 – 3 –

NOTE 102 These devices may sometimes be operated against short-circuit. The different classes of earthing

switches are related to the number of short-circuit making operations.

NOTE 103 For special applications such as fault initiating earthing switches the test procedures and the number

of tests may be agreed upon between the manufacturer and the user.

3.4.105.1
earthing switch class E0
Replace the existing definition by the following new definition:

earthing switch suitable for applications in distribution and transmission systems fulfilling the
general requirements of this standard, without a short-circuit making capability

3.4.105.2
earthing switch class E1
Replace the existing definition by the following new definition:
earthing switch suitable for applications in distribution and transmission systems fulfilling the
general requirements of this standard, with the capability to withstand two short-circuit making
operations
3.4.105.3
earthing switch class E2
Replace the existing term, definition and note by the following new term, definition and note:
earthing switch class E2 (for earthing switches up to and including 52 kV)
earthing switch suitable for applications in distribution and transmission systems fulfilling the
general requirements of this standard, with the capability to withstand five short-circuit making
operations
NOTE The increased number of making operations in Class E2 is restricted to voltages up to and including 52 kV
only depending on the operating conditions and the protection systems typical to such networks.
Add, after definition 3.4.105.3, the following new definitions 3.4.105.4, 3.4.105.5 and
3.4.105.6:
3.4.105.4
earthing switch class M0 (for earthing switches)
earthing switch suitable for applications in distribution and transmission systems fulfilling the
general requirements of this standard, with the capability to withstand 1 000 operating cycles
3.4.105.5
combined function earthing switch

earthing switch having a common contact system for earthing and at least one of the following
functions:
 disconnecting;
 making and/or breaking of load currents;
 making and/or breaking of currents up to the rated short-circuit current

NOTE 101 Earthing switches with dependent manual operations should not be rated for short circuit making

capability.
4.5 Rated short-time withstand current (I )

k
Replace the existing text of this subclause by the following new text:

Subclause 4.5 of IEC 62271-1 is applicable with the following addition.

The rated short-time withstand current of an earthing switch forming an integral part of a

combined function earthing switch shall be equal to the rated short-time withstand current of

the combined function earthing switch, unless otherwise specified.

4.6 Rated peak withstand current (I )
p
Replace the existing text of this subclause by the following new text:
Subclause 4.6 of IEC 62271-1 is applicable with the following addition.
The rated peak withstand current of an earthing switch forming an integral part of a combined
function earthing switch shall be equal to the rated peak withstand current of the combined
function earthing switch, unless otherwise specified.
4.101 Rated short-circuit making current
Add the following new text after the existing text of this subclause:
The rated short-circuit making current of an earthing switch forming an integral part of a
combined function earthing switch shall be equal to the rated peak making current of the
combined function earthing switch, unless otherwise specified.
4.107 Rated values of electrical endurance for earthing switches
Replace the existing text by the following new text and Table 7:
Table 3b provides a classification of earthing switch for electrical endurance.
Table 7 – Classification of earthing switch for electrical endurance
Class Type of earthing switch
E0 Earthing switches with no making capability

E1 Earthing switches with capability to withstand two short-circuit making operations
E2 Earthing switches with capability to withstand five short-circuit making operations

6.101 Test to prove the short-circuit making performance of earthing switches
Replace the existing Subclauses 6.101.1, 6.101.2 and 6.101.3 by the following new
Subclauses 6.101.1, 6.101.2, 6.101.3, 6.101.4, 6.101.5, 6.101.6, 6.101.7, 6.101.8, 6.101.9,
6.101.10 and 6.101.11:
6.101.1 General test conditions
Earthing switches of class E1 or E2 according to definition 3.4.105, having a short-circuit
making current capability, shall be subjected to two (class E1) or five (class E2) making
operations respectively, in a making test series in accordance with the procedures of 6.101.7.

62271-102 Amend.1 © IEC:2011 – 5 –

In case of combined function earthing switches, the short-circuit making tests shall first be

performed in the contact positions for other functions, in accordance with the relevant

standards, followed by the short-circuit making tests of the earthing function, without

intermediate maintenance.
Alternatively, the short-circuit making tests of the combined function earthing switch according

to the specified class can be performed on a new combined function earthing switch preceded

by at least one short-circuit making test of the other function followed by the short-circuit

making tests of the earthing function without intermediate maintenance.

6.101.2 Arrangement of the earthing switch for tests

The earthing switch shall be tested under the representative conditions of installation and
use, concerning the connections, support, enclosure and dimensions.
Its operating device shall be operated in the manner prescribed and in particular, if it is
electrically, hydraulically or pneumatically operated, it shall be operated at the minimum
supply voltage or pressure.
For gas-filled earthing switches, the tests shall be performed at the minimum functional
pressure of the gas for insulation and making operation.
NOTE 1 For convenience of testing the supply voltage to the coil for the closing operation may be increased to
obtain a consistent closing time, provided it does not increase the closing speed of the contacts.
NOTE 2 For convenience of testing in order to obtain accurate closing times an electrically or pneumatically
released latch may be introduced at the toggle point.
