Functionality
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.
