Data Set Class
Named list of ordered references to one or more Functionally Constrained Data
(FCD) or Functionally Constrained Data Attributes (FCDA). Used to group
commonly used data objects for easy retrieval.
Device
Piece of equipment or tool designed to perform one or more specific tasks.
Diameter
Refers to a 1 1/2 breaker arrangement and comprises the complete switchgear
between the two busbars, i.e. the 2 lines and the 3 circuit breakers with all
related isolators, earthing switches, CTs and VTs. It has some common
functionality and relationship both for operation, maintenance and extensions.
Distributed Functions
Functions performed by collaboration of two or more logical nodes that are
located in different physical devices. Since all functions communicate in some
way, the definition of a local or distributed function is not unique but depends on
the definition of the functional steps to be performed until the function is
completed. In the case of loss of one LN or one included communication link, the
function may be blocked completely or show a graceful degradation, as
applicable.
Distribution
The part of the power system operating at voltages typically up to 69 kV.
E
Electronic Current Transducer
Transducer in the primary plant that measures system current and provides low-
level analog and/or digital output(s).
Electronic Voltage Transducer
Transducer in the primary plant that measures system voltage(s) and provides
low-level analog and/or digital output(s).
Engineering
First phase of a project, i.e. detail design.
Engineering Tools
These support the creation and documentation of the conditions for adapting the
SAS to the specific substation and customer requirements. The engineering tools
are divided into project management, parameterization and documentation tools.
Equipment
Entity that performs an energy transport function, for example: transformer,
circuit breaker, line. It may be stand-alone or interfaced to an automation system
via an integral device or associated external device.
