Figure. 5.4.4 - 176. Second voltage window two tap steps from the first voltage window.
It is recommended that the operating time for the second (fast) window is in inverse mode, although it
can also be set to the definite operating mode. Therefore, the more the measured voltage exceeds the
threshold, the faster the operating time will be.
The AVR inverse operating time is calculated with the following equation:
For example, if
U >>/<<< time delay has been set to 40 seconds and the measured voltage difference
from the set target is 4 %, using the formula above the operating time can be determined to be 10
seconds (40s / 4)
