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

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

Earthing switches of class E1 or E2 according to definition 3.4.105, having a short-circuit

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.

NOTE 3 Earthing switches with independent manual operation may be operated by an arrangement provided for

the purpose of making remote control possible.

NOTE 4 For testing purposes, it may be necessary to measure the travel characteristics, for example by using a

travel recorder.
6.101.3 Test frequency

Earthing switches shall be tested at rated frequency, with a tolerance of ± 10 %.

However, tests with a peak factor of 2,6 or above, at a supply frequency of 50 Hz or 60 Hz

cover the requirements of both frequencies.
6.101.4 Test voltage
The test voltage shall be as follows:

a) For three-phase tests, the average value of the applied voltage phase-to-phase shall not

be less than the rated voltage U and shall no
