Hi David,
What changes should I do for a 3-phase, 4-wire system and 3-phase, 3-wire system? Similarly, should I make any change other than opening JP3A and JP4A when I change to Rogowski coil from CT? I know the maximum permissible signal level at analog inputs is 0.5V peak with respect to AGND. But what is the limit on the current flowing to analog pins of ADE?
