Once the tuning process has been successfully completed, the zero sequence voltage is
saved with absolute value and phase (Figure 75: with Une_ref/Usync displayed).3.3 Menu item Regulation

Figure 75: Tolerance range that triggers tuning process
If the voltage remains within the trip circuit (3), tuning not initiated.
If the absolute value and/or phase changes value that bigger than the specified tol-
erance result grid switching, the REG-DP/ REG-DPA will start new search process.3.Page 99
