Reverse .
The relay provides 2 additional signals to the start and trip signals:
•
V0 activated, indicates that the measured residual voltage is higher than the polarization
voltage.
•
Directionality, indicates that the residual current is inside the adjusted intervention area.
If the Directionality parameter is adjusted to NO, neither the residual voltage and the direction of
the residual current won’t be evaluated, keeping these previous signals deactivated.
Besides the Directionality parameter, the ‘Reverse Directionality’ signal permits being configured
to a digital input to change the function to reverse directionality when the DI is active despite the
function was adjusted as direct directionality.
