EN 61936-1:2010

Power installations exceeding 1 kV a.c. - Part 1: Common rules

IEC 61936-1:2010 provides common rules for the design and the erection of electrical power installations in systems with nominal voltages above 1 kV a.c. and nominal frequency up to and including 60 Hz, so as to provide safety and proper functioning for the use intended. For the purpose of interpreting this standard, an electrical power installation is considered to be one of the following: a) Substation, including substation for railway power supply; b) Electrical installations on mast, pole and tower; Switchgear and/or transformers located outside a closed electrical operating area; c) One (or more) power station(s) located on a single site. The installation includes generators and transformers with all associated switchgear and all electrical auxiliary systems. Connections between generating stations located on different sites are excluded; d) The electrical system of a factory, industrial plant or other industrial, agricultural, commercial or public premises. The electrical power installation includes, among others, the following equipment: rotating electrical machines; switchgear; transformers and reactors; converters; cables; wiring systems; batteries; capacitors; earthing systems; buildings and fences which are part of a closed electrical operating area; associated protection, control and auxiliary systems; large air core reactor. NOTE: In general, a standard for an item of equipment takes precedence over this standard. This standard does not apply to the design and erection of any of the following: - overhead and underground lines between separate installations; - electric railways; - mining equipment and installations; - fluorescent lamp installations; - installations on ships and off-shore installations; - electrostatic equipment (e.g. electrostatic precipitators, spray-painting units); - test sites; - medical equipment, e.g. medical X-ray equipment. This standard does not apply to the design of factory-built, type-tested switchgear for which separate IEC standards exist. This standard does not apply to the requirements for carrying out live working on electrical installations. This second edition cancels and replaces the first edition, published in 2002. It constitutes a technical revision. The main changes with respect to the previous edition are listed below: - new table of references for additional agreements between manufacturer/contractor/planer and user/orderer/owner (4.1.2); - addition of minimum clearances in air not standardized by IEC but based on current practice in some countries (Annex A); - deletion of nominal voltages (Table 1, Table 2, Clause 5); - addition of regulations for fuses (6.2.15); - simplification of regulations for escape routes (7.5.4); - deletion of special regulations for operating aisles (7.5.4); - modification of clearances for fire protection (Table 3); - modification of safety criteria for earthing systems (10.2.1); - modified curves of permissibly touch voltages (Figure 12, Annex B); - deletion of numbering of subclauses without headlines; - change of "should" to "shall" in many cases or change of subclauses with "should" to a note. The contents of the corrigendum of March 2011 have been included in this copy.

Standard until they have been removed.
Clause Deviation
General France
In France many laws and decrees are mandatory for the design, the construction, the
verification and the control of HV installations. All the French safety and legal requirements,
mainly driven by the ministry of industry (arrêté du 17 mai 2001), the ministry of labour (décret
du 14 novembre 1988) and the grid codes for HV and MV public networks are incorporated in
two national standards; NFC 13-100 and NFC 13-200. Both NFC 13-100 and NFC 13-200 are
globally in line with EN 61936-1. Their application is mandatory in France and they cannot be
superseded by the European Standard, which provide only general rules.
EN 61936-1 does not cover a large part of the field of the French regulation. It cannot be used
in France as a contracting basis between various players involved in HV installation business,
since it may create difficulties, interpretation problems, and confused situations.
The main additional rules and deviations from EN 61936-1 are covered by NFC 13-100 and
NFC 13-200.
Additional rules:
limits of private installations and interfaces with the HV public grid;
mandatory requirements for private installations including power generation;
mandatory requirements for HV substations interfacing private installation to public grid;
rules for architecture design of HV private installations;
detailed rules concerning neutral systems;
detailed rules concerning design and construction of a global earthing system;
additional rules concerning the protection against direct and indirect contact;
additional rules concerning the protection against fire and explosion;
rules dedicated to the protection against over voltages, under voltages, temporary loss of
supply, harmonics;
protection against the noise including French directives;
detailed rules dedicated to HV cables sizing;
additional rules for selection, installation and protection of generators, motors and
transformers;
dedicated rules for metering according to utility requirements;
dedicated rules to the data to be exchanged with the grid operator system and associated
communication equipment;
design and construction of buildings according French directives;
verification and control of HV installations according to French legislation;
detailed information concerning the classification of environmental conditions.
Main A-deviations: see appropriate (sub)clause number.
