Step:
Step 1. According to the CT testing project description of the table 2.1 to wiring(For all the CT structures,please refer to the description of appendix D for the actual connection mode)
Step 2. The other windings of the same CT should be opened,CT's primary side to grounding, equipment should be also to ground
Step 3. Power on and prepare parameters Settings.
Step 4. Then switch cursor to the "start" button to start
