Feeder Equipment

IEC 61850-7-3:2010+A1:2020 is applicable to the description of device models and functions of substations and feeder equipment. It specifies constructed attribute classes and common data classes related to substation applications. In particular, it specifies common data classes for status information, common data classes for measured information, common data classes for control, common data classes for status settings, common data classes for analogue settings and attribute types used in these common data classes. This second edition defines new common data classes used for new standards defining object models for other domains based on IEC 61850 and for the representation of statistical and historical data.
