Functionality
GUID-6AF2219A-264F-4971-8D03-3B8A9D0CB284 v4
Different protection functions within the protection IED operates on the basis of measured
voltage at the relay point. Some example of protection functions are:
•
Distance protection function.
•
Undervoltage function.
•
Energisation function and voltage check for the weak infeed logic.
These functions can operate unintentionally, if a fault occurs in the secondary circuits between
voltage instrument transformers and the IED. These unintentional operations can be prevented by
VDSPVC.
