Set the rated primary current of the Earth/Ground CT.
Note: The CT secondary should be connected to 5A or 1A CT input terminal of the relay according
to Primary CT type. The display current is calculated by the formula:
Current at CT input terminal / CT input terminal type x CT Pri (setting above)
For example if:
Current at CT input terminal = 3A,
CT input terminal type = 5A,
CT Pri = 200A,
The display value = 3/5 x 200 = 120A
