Transformer connections to three current transformers, cable-type current transformer and
broken delta winding, maximum precision for sensitive ground fault detection
Important! Grounding of the cable shield must be effected at the cable side
For busbar-side grounding of the current transformers, the current polarity of the device is changed via
address 0201. This also reverses the polarity of the current input IN/INs. When using a cable-type current
transformer, the connection of k and I at F8 and F7 must be exchanged.

Figure C-11 Current transformer connections to two phase-current transformers and a ground-current
transformer; the ground current is taken via the highly sensitive and sensitive ground input.
