The relay trips t seconds after the pickup setting value is exceeded, t being the
Definite Time configured for this function. To be operational, this unit requires the
voltage of any of the phases to be at least 0.1 V in the secondary.
Figure 2-25 shows the logical diagram for the definite time unbalanced voltage
function.
