Installations électriques en courant alternatif de puissance supérieure à 1 kV - Partie 1: Règles communes

This part of IEC 61936 provides, in a convenient form, 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.

This standard applies to all high voltage installations except as stated otherwise in some cases specified in other parts of IEC 61936.

This standard does not apply to the design and erection of any of the following:

- overhead and underground lines between separate installations;

- electric railways (but not the substation feeding a railway system);

- mining equipment and installations ;

- fluorescent lamp installations;

- installations on ships and off-shore installations;

- electrostatic equipment;

- 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 installation
