2.3.3 Connection between CT Secondary Circuit and the GRT100
The GRT100 is provided with 2 or 3 three-phase current input terminals depending on the relay
models.
To validate the phase angle matching mentioned above and input in-phase current of each
winding to the relay, connect the CT secondary circuits to the current input terminal of the relay
as follows;
As shown below, the phases used in the phase angle setting (indicated with arrowhead) must be
connected to the AC input terminals with the least number in the terminal group such as 1, 9, 17,
then other two phases should be connected to the terminals with larger number clockwise from
the setting phase, such as 3 and 5, 11 and 13, or 19 and 21.
