V< (Under-Voltage Phase Threshold for Ground Fault)
(Address 70) This register defines the under-voltage threshold for exact phase detection in case of a 1-phase-
to-ground fault. This is set as a percentage value of the network rated voltage.

Delta Pulse Off-On (3I0 Delta)
(Address 72) This register defines the threshold value of the ground-fault current between pulse ON and pulse
OFF. This register is set as percentage value of the rated ground-current threshold value.

Pulse-on Duration (TPulse On)
(Address 73) This register defines the duration of the pulse ON, in other words the switch-on duration of the
capacitor. It is expressed in milliseconds.
