Setup method B (alternate)
This approach adds the current from each phase of the CT1 and CT2 together to represent the total winding 1 current. The
procedure is outlined as follows.
1. Enter the settings for each set of CTs in the
SYSTEM SETUP  AC INPUTS  CURRENT BANK settings menu, as shown for
method A.
2. Configure Source n (Source 1 for this example) to be used as the summed current in Winding 1 in the
