Technical data
Accuracies and reaction times
Operating area
MainsPro provides the below mentioned accuracies and reaction times in case that the measured
voltage on all 3 phases is within the green area on the picture below. Outside of the green area,
MainsPro provides the expected performance (i.e. trips in case of voltage overreaching the green area
border), but the behaviour, accuracies and reaction times may not be guaranteed.
