This part of IEC 61936 provides requirements for the design and the erection of electrical power installations in systems with nominal voltages exceeding 1 kV AC 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 document, an electrical power installation is considered to be one of the following:
a) substation, including substation for railway power supply;
b) electrical power 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 electrical power 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;
e) electrical power installations on offshore facilities for the purpose of generation, transmission, distribution and/or storage of electricity;
f) transition towers/poles (between overhead lines and underground lines).dition 3.0 2021-07 INTERNATIONAL STANDARD NORME INTERNATIONALE colour inside Power installations exceeding 1 kV AC and 1,5 kV DC – Part 1: AC Installations électriques de puissance de tension supérieure à 1 kV en courant alternatif et 1,5 kV en courant continu – Partie 1: Courant alternatif IEC 61936-1:2021-07(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2021 IEC, Geneva, Switzerland All rights res
