Organization: IEC
Publication Date: 1 October 2016
Status: active
Page Count: 154
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 the assemblies of the main electrical functional units of a high-voltage/low-voltage distribution substation, duly interconnected, for alternating current of rated operating voltages above 1 kV and up to and including 52 kV on the highvoltage side, service frequency 50 Hz or 60 Hz. This assembly is to be cable-connected to the network, and intended for installation within an indoor or outdoor closed electrical operating area.

A Compact Equipment Assembly for Distribution Substation (CEADS) as defined in this document is designed and tested to be a single product with a single serial number and one set of documentation.

The functions of a CEADS are:

• switching and control for the operation of the high-voltage circuit(s);

• protection of the high-voltage/low-voltage transformer functional unit;

• high-voltage/low-voltage transformation;

• switching and control for the operation and protection of the low-voltage feeders.

However relevant provisions of this document are also applicable to designs where not all of these functions exist (e.g. equipment comprising only high-voltage/low-voltage transformation and switching and control for the operation and protection of the low-voltage feeder functions or equipment without switching and control for the operation of the high-voltage circuit(s)).

NOTE For the purpose of this document a self-protected transformer is considered not as a CEADS, but as a functional unit, designed and type tested to its own product standard IEC 60076-13:2006
