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 transformer substation, duly interconnected, for AC voltages up to and including 52 kV on the high-voltage side and service frequency 50 Hz or 60 Hz. The CEADS is cable-connected to the high-voltage network for indoor and outdoor applications of restricted access.
A 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:
- high-voltage/high-vo
- switching and control for the operation of the high-voltage circuit(s);
- switching and control for the operation of the low-voltage circuit(s);
- protection of the power transformer functional unit.
The main functions are integrated in the following functional units:
- high-voltage functional unit;
- power transformer functional unit;
- low-voltage functional unit.
NOTE For the purpose of this document a self-protected transformer is not considered as a CEADS, but as a functional unit, designed and type tested to its own product standard IEC 60076-13:2006.
