Technical Specification

Scope

This document specifies the service conditions, rated characteristics, general structural requirements and test methods of prefabricated substations used in AC and DC electric traction systems, which are
– connected by insulated cable,
– to be operated from inside (walk-in type) or outside (non-walk-in type)
NOTE prefabricated substations for railway applications are typically of the walk-in type due to the rating and resulting dimensions of the AC or DC traction switchgear.
– for alternating current of rated voltages above 1 kV and up to and including 52 kV on the high voltage side,
– in DC traction applications with a DC traction switchgear and rectifier and
– possibly with one or more transformers for service frequencies up to and including 60 Hz
– for outdoor installation – at locations with public accessibility and – where protection of personnel is
Prefabricated substations for railway applications can be situated at ground level or partially or completely below ground level.
In general a prefabricated substation comprises an enclosure containing the following electrical components:
– power transformers;
– high voltage and low voltage switchgear and controlgear;
– high voltage and low voltage interconnections;
– auxiliary equipment and circuits.
However, relevant provisions of this standard are applicable to designs where not all these electrical components exist (for example, an installation consisting of power transformer and low voltage switchgear).
Non-prefabricated substations should comply with the applicable requirements of EN 61936 1:2010 + A1:2014.
