Power installations exceeding 1 kV AC and 1,5 kV DC - Part 1: AC
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).*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 1 – In general, equipment standards take precedence over the requirements of this document.*This document does not apply to the design and erection of any of the following:*- overhead and underground lines between separate electrical power installations;*- electrified railway tracks and rolling stock;*- mining equipment and insta ...
