Micom P634 - Fixed-Time Warning Stage; Fixed-Time Tripping Stage; Variable-Time Tripping Stage

3.28.3 Fixed-time Warning Stage
The overfluxing value (V/f) is monitored to determine whether it exceeds a set
threshold. A timer stage is triggered when the overfluxing value exceeds this
threshold and a signal is issued when the time delay has elapsed.
