Current Transformer

Current transformer:

Current transformer is nothing but a step-up transformer, whose primary has less turns typically the line consider as the primary winding and the secondary has more turns. That’s why we should keep CT secondary terminal in the closed condition.

Primary winding < Secondary Winding

Note: As the voltage increases the current decreases. That’s why we gets such a Current ratio 400/5
