1. The secondary output S1 of CT for R-phase detection must be connected to the terminal
board R_S1, and the S2 outgoing line must be connected to the terminal board R_S2.
2. The secondary output S1 of CT for S-phase detection must be connected to the terminal
board S_S1, and the S2 outgoing line must be connected to the terminal board S_S2.
3. The secondary output S1 of CT for T-phase detection must be connected to the terminal
board T_S1, and the S2 outgoing line must be connected to the terminal board T_S2.
NOTE:
1. When compensating a three-phase system, single CT detection can be set
up (only the R-phase CT is connected).
2. Corresponding setting shall be set up in accordance with CT wiring under
compensation mode; otherwise, the compensation will not be working.
3. The CT wiring shall be fastened to avoid open circuit, which will lead to
high-voltage risk and secondary circuit burning.
