Figure 404: Alternative connection example of current transformers of Type 2
The CT secondary currents often differ from the rated current at the rated load
of the power transformer. The CT transforming ratios can be corrected on both
sides of the power transformer with the
CT ratio Cor Wnd 1 and CT ratio Cor Wnd 2
settings.
