20 Gas-filled medium-voltage designs use to have design pressures below 500 kPa, as mentioned
21 for example in the introduction of EN 50187.
22 2 Normative references
23 Delete the normative reference IEC 62271-203:2011.
24 Add the following normative reference:
25 ISO 4126-2, Safety devices for protection against excessive pressure – Part 2: Bursting disc
26 safety devices
27 3 Terms and definitions
28 Replace term 3.6.101 and its definition by following one:
29 3.6.101 loss of service continuity category (LSC)
30 category defining the possibility to keep other high-voltage compartments
31 and/or functional units energized when opening its connection compartment or any other of its

34 Note 1 to entry: The LSC category describes the extent to which the assembly is intended to remain operational
35 where access to a high-voltage compartment is provided. The extent to which it is considered necessary to open
36 high-voltage compartments of an installation in service might be dependent on several aspects (refer to 9.101).
37 Note 2 to entry: The LSC category does not describe or relate to different levels of reliability of assemblies (refer
38 to 9.101).
39 Note 3 to entry: In relation to providing access to high-voltage compartments and the associated service continuity,
40 four categories are defined: LSC1, LSC2, LSC2A, LSC2B (refer to Annex D).
41 6 Design and construction
42 6.10 Pressure/level indication
43 Replace the sentence of 6.10 by following text:
44 Subclause 6.10 of IEC 62271-1:2017 is applicable with the following addition to 6.10.1 of
45 IEC 62271-1:2017.
46 For gas-filled compartments where the minimum functional pressure exceeds 200 kPa (absolute
47 pressure at 20 °C) an indication shall be provided when the absolute pressure at 20 °C has
48 fallen below the minimum functional level (refer to 3.6.114).
49 NOTE 1 The indication might include monitoring of pressure (density).
50 Closed pressure systems with minimum functional pressure above 200 kPa (absolute pressure) shall
51 have a defined alarm pressure (density) level.
52 NOTE 2 Alarm pressure (density) is defined in IEC 62271-1:2017, 3.6.5.3 and 3.6.5.4
53 An example of pressure coordination chart is shown in Figure E.1.
54 6.102.2 Covers and doors
55 Replace the indent b) by following one:
56 b) Covers and doors that give access to interlock-controlled accessible or procedure-based accessible
57 compartments
58 These covers and doors shall be provided if there is a need to access the compartment for normal
59 use as stated by the manufacturer. These covers and doors shall not require tools but may
60 additionally require the manipulation of some fixing elements for their opening or removal and shall
61 have the following features:
62 – interlock controlled accessible compartments shall be provided with interlocking devices so that
63 opening of the compartment shall only be possible when the high-voltage parts contained in the
64 compartment being made accessible are isolated and earthed, or are in the disconnected
65 position with corresponding shutters closed;
66 – procedure-based accessible compartments shall be provided with provision for locking, e.g.
67 padlocking. Suitable procedures should be put in place by the user to ensure that a procedure-
68 based accessible compartment is opened only when the high-voltage parts contained in the
69 compartment being made accessible are isolated and earthed, or in the disconnected position
70 with corresponding shutters closed. Procedures may be dictated by legislation of the country of
71 installation or by user safety documentation.
72 If interlock-controlled or procedure-based accessible compartments have covers that can be opened
73 by tools, other than those that are interlocked or locked, proper procedures or specific warning labels
74 should be applied.
75 6.103.1 General
76 Replace NOTE 1 by following text:
77 NOTE 1 Only interlock-controlled accessible compartments and procedure based accessible compartments are
78 considered when defining the LSC category of a functional unit

IEC CDV 62271-200 A1 © IEC 2023 4 17C/903/CDV

79 Replace the fifth paragraph after NOTE 1 by following text:
80 The LSC category can only be assigned to functional units that include a connection
81 compartment. This implies that e.g. a bus-sectionaliser or bus-coupler functional unit will have
82 no LSC category, refer to Figure 8 and Figure 9.
83 6.103.2.1 General
nd rd
84 Replace “normally filled” by “filled” at the 2 paragraph 3 line as follows:
85 Gas-filled compartments, when permanently pressurised in service, are subjected to particular
86 conditions of service which distinguish them from compressed air receivers and similar storage vessels.
87 These conditions are such that gas-filled compartments are filled with a gas that is stable and non-
88 corrosive in the conditions that prevail inside the compartment. Measures to maintain the gas in this
89 condition with only small fluctuations in pressure are fundamental to the operation of the assembly and
90 the compartments will not be subjected to internal corrosion. Therefore, when these measures are taken,
91 there is no need to make allowances for the two factors (fluctuations in pressure and internal corrosion)
92 in determining the design of the compartments.
nd
93 Add the following NOTE 1 after 2 paragraph:
94 NOTE 1 The non-corrosive conditions that prevail inside gas-filled compartments are maintained by appropriate
95 measures such as filter material to adsorb humidity and decomposition products, if any.
96 Replace the last paragraph, reproduced here below, by text that follows:
97 Gas-filled compartments with design pressures higher than 300 kPa (relative pressure) shall be
98 designed according to the pressure requirements of IEC 62271-203.
99 Materials used in the construction of enclosures should be of known and certified minimum
100 physical properties on which pressure tests are based (see 7.103). The manufacturer is
101 responsible for the selection of the materials and the maintenance of these minimum properties,
102 based on certification of the material supplier or tests conducted by the manufacturer, or both.
103 The NOTE becomes NOTE 2.
104 6.103.2.2 Design
105 Replace the 1st paragraph by following text:
106 The design of a fluid filled compartment shall be based on the nature of the fluid, the design
107 temperature and the design pressure as defined in this document.
108 Replace the 3rd and 4th paragraph by following text:
109 The design pressure of a compartment is equal to the maximum pressure difference between
110 the fluid inside the compartment at design temperature that the fluid used for insulation can
111 reach under specified maximum service conditions, and the surrounding media, like ambient air
112 or insulation fluids in other compartments. Therefore, the design pressure calculation shall also
113 consider:
114 a) the full differential pressure possible across the compartment walls or partitions, including
115 any evacuation process if used during filling or maintenance operations;
116 b) the resulting pressure in the event of an accidental leak between the compartments in the
117 case of adjacent compartments having different service pressures.
118 Add after last paragraph the following text:

IEC CDV 62271-200 A1 © IEC 2023 5 17C/903/CDV

119 The design of the fluid-filled compartment shall also take into account the possibility of the
120 occurrence of an internal arc fault.
121 In normal service the pressure inside a gas-filled compartment varies from the filling pressure
122 p with the gas temperature variations, at different service conditions, and possible leaks.

123 Several pressure values shall be coordinated when designing a fluid-filled compartment. An
124 example is shown in Figure E.1

126 Delete the following 3 paragraph that now is moved to 6.10:
127 For gas-filled compartments where the minimum functional pressure exceeds 200 kPa (absolute
128 pressure) an indication shall be provided when the pressure at 20 °C has fallen below the
129 minimum functional level (refer to 3.6.114).
130 6.103.2.4 Pressure relief of fluid-filled compartments
131 Replace the second sentence by following one:
132 Pressure relief devices shall operate with relative pressure above 1,3 times the design
133 pressure.
134 7 Type tests
135 7.102.2 Mechanical and electromechanical interlocks and locking devices

136 Replace the sentence below the 5 indents of 4 paragraph by the following text:
137 The force shall be applied at the midpoint, of the gripping part of the handle or actuator with
138 the following considerations:
139 – For handles consisting of one or more levers, the gripping part shall be defined by the manufacturer
140 before testing. In this case, two different scenarios are considered:
141 • if intended for gripping with one hand, the gripping part shall not extend more than 100 mm from
142 the end of the lever;
143 • if intended for gripping with two hands next to each other, the gripping part shall not extend more
144 than 200 mm from the end of the lever.
145 – For handles where the lever is extensible or sliding, the lever shall be at longest possible length,
146 and the full force shall be applied to only one of the gripping parts of the lever(s), if more than one
147 exists.
149 7.103.1 Pressure withstand test for gas-filled compartments with pressure relief
150 devices
151 Replace the content of this subclause by:
152 Each design of a gas-filled compartment equipped with its pressure relief devices(s) shall be
153 subjected to pressure tests as follows:
154 – Adjacent compartments (if any) shall be set at a pressure not higher than the minimum functional
155 pressure of those compartments. If the manufacturer's instructions reference allow for maintenance
156 of those co
