Function-Group Type Voltage/current 3-Phase
Overview
All functions for protection and supervision of a protected object or equipment allowing 3-phase current and
voltage measurement can be used in the function group Voltage-current 3-phase. The function group also
contains the operational measurement for the protected object or equipment (on this topic, see chapter
9 Measured Values, Energy Values, and Supervision of the Primary System).
You will find the Voltage-current 3-phase function group under each device type in the Global DIGSI 5 library.
You will find all protection and supervision functions that you can use for this function-group type in the func-
tion group Voltage-current 3-phase. These functions are described in chapter 7 Protection and Automation
Functions.
You can find additional information on the embedding of the functions in the device in chapter 2 Basic Struc-
ture of the Function. You can find the function scope of the application templates for the various device types
in the chapter 4 Applications.
Structure of the Function Group
The function group always contains the following blocks:
•
Protected object/equipment data (FB General)
•
Operational measured values
•
Process monitor
•
Output logic of the function group
•
Reset LED group
These blocks are essential for the function group under all circumstances, so they cannot be loaded or deleted.
You can load the protection and supervision functions required for your application in the function group. The
functions are available in the Global DIGSI 5 library. Functions that are not needed can be deleted from the
function group.
The following figure shows the structure of the function group Voltage-current 3-phase.
