Ideal For
Not Recommended For
For current transformers, connect secondary terminals 1S1/1S2 for the main winding, and 2S1-2S2 for protection winding if present. Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary winding at one point. Follow IEC 61869 / IEEE C57.13 terminal conventions.
