Organization: IEC
Publication Date: 1 June 2006
Status: inactive
Page Count: 148
ICS Code (High voltage switchgear and controlgear): 29.130.10
scope:

This part of IEC 62271 specifies the service conditions, rated characteristics, general structural requirements and test methods of HV/LV or LV/HV prefabricated substations, which are cable-connected, to be operated from inside (walk-in type) or outside (non-walk-in type) for alternating current of rated voltages above 1 kV and up to and including 52 kV on the HV side, and for one or more transformers for service frequencies up to and including 60 Hz for outdoor installation in locations with public accessibility.

Prefabricated substations can be situated at ground level or partially or completely below ground level.

In general, a prefabricated substation comprises the following main components (functions):

- enclosure;

- power transformers;

- HV and LV switchgear and controlgear;

- HV and LV interconnections;

- auxiliary equipment and circuits.

However, relevant provisions of this standard are applicable to designs where not all these components exist (for example, an installation consisting of power transformer and LV switchgear).

NOTE Non-prefabricated substations should comply with the applicable requirements of IEC 61936-1.
