134 A-deviations
135 A-deviation: National deviation due to regulations, the alteration of which is for the time being outside the
136 competence of the CENELEC national member.
137 This European Standard does not fall under any Directive/Regulation of the EU.
138 In the relevant CEN and/or CENELEC countries, these A-deviations are valid instead of the respective
139 provisions of the European Standard until the national situation causing the A-deviation has changed.
140 Clause Deviation
141 General France
142 In France many laws and decrees are mandatory for the design, the construction, the verification, and the
143 control of HV installations.
144 The application of the French safety and legal requirements, mainly driven by the ministry of industry (e.g.
145 arrêté du 17 mai 2001), the ministry of labor (Décrets n° 2010-1017 du 30 août 2010 et 2010-1118 du 22
146 septembre 2010) and the Technical Reference Documents (DTR) for HV and MV public networks is
147 mandatory in France and they cannot by superseded by the EN, which is providing only general rules.
148 The additional rules to be compliant with the French legal requirements are covered by three national
149 standards NF C 13-100, NF C 13-200 and NF C 11-201.
150 EN IEC 61936-1 cannot be used in France as a contracting basis between various players involved in HV
151 installation, since there can be discrepancies with mandatary regulations.
152 Mandatory rules of conception and installation:
153 • rules for HV substations interfacing private installation to public grid;
154 • rules for structural design of HV installations;
155 • rules concerning neutral systems;
156 • rules concerning design and construction of a global earthing system;
157 • rules concerning the protection against direct and indirect contact;
158 • rules concerning the protection against fire and explosion;
159 • rules concerning operation on HV installations;
160 • rules dedicated to the protection against over voltages, under voltages, temporary loss of supply,
161 harmonics;
162 • rules concerning protection against the noise;
163 • rules dedicated to HV cables sizing;
164 • rules for selection, installation and protection of generators,
