DIN EN 61936-1:2014-12

This standard contains 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. With this A1 included into the new edition, offshore wind power farms and the corresponding specifications have been added to the scope. The responsible committee is DKE/K 222 "Errichten von Starkstromanlagen über 1 kV und deren Erdung" ("Erection of electrical power installations exceeding 1 kV and their earthing") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
