The Threshold min/max parameter is the criterion by which a phase-to-phase voltage unbalance is meas-
ured. The device calculates the ratio between the minimum (V
min
) and the maximum (V
max
) phase-to-phase
voltage.
Enter the lower limit of the maximum phase-to-phase voltage (V
max
) with the parameter Release
threshold. This specifies the lower limit of the operating range of this function.
