 N TS 62271-304 CORR 1

Annotation

This International Standard is applicable to high-voltage switchgear and controlgear (scope of IEC SC 17A) and assemblies thereof (scope of IEC SC 17C) and specifies equipment for digital communication with other parts of the substation and its impact on testing. This equipment for digital communication, replacing metal parallel wiring, can be integrated into the high-voltage switchgear, controlgear, and assemblies thereof, or can be an external equipment in order to provide compliance for existing switchgear and controlgear and assemblies thereof with the standards of the IEC 61850 series.

This International Standard is a product standard based on the IEC 61850 series. It deals with all relevant aspects of switchgear and controlgear, and assemblies thereof with a serial communication interface according to the IEC 61850 series. In particular it defines:

a) A selection of the information models from the IEC 61850 series that shall be supported by such switchgear and controlgear, and assemblies thereof.

b) Conformance classes for the set of communication services that shall be supported by the switchgear and controlgear, and assemblies thereof.

c) Modifications and extensions to type and routine tests of switchgear and controlgear, and assemblies thereof that are required due to the serial communication interface.

d) An extension of the IEC 61850 series’ object model for switchgear monitoring.
