For current transformers, adhere to IEC 61869-2 terminal markings: primary P1/P2, secondary 1S1/1S2 (protection winding 2S1-2S2 if applicable). Never open-circuit the secondary of a CT while energized - hazardous voltage may occur. Ground the secondary circuit at one point only. Ensure correct polarity for differential or directional protection. Verify rated burden and accuracy class before energizing.
