Function Groups and Function Elements
The default overcurrent application template includes functions that are typically used in this type of device.
The appropriate analogue inputs are provided in the 7SR5110 overcurrent/earth fault relay and 7SR5111 direc-
tional overcurrent/earth fault relays.
Figure 2-4 and Figure 2-5 below provide a summary of the functions available using the analogue inputs.
Functions that do not use analogue input measurands are also provided, these include:
•
52 CB and plant control
•
74 Trip/close circuit supervision
•
79 Autoreclose functionality
•
User logic schemes
Example – 7SR5110
The 7SR5110 overcurrent application templates are summarized in Figure 2-4.
