See full list on cnzentar.com Therefore, the secondary winding of the zero sequence current transformer has no signal output, and the actuator does not operate. It is circulated in the phase windings of the delta connection as shown in the figure below.the zero sequence currents are produced due to the existence of zero sequence voltage.

When the ground fault occurs, the vector sum of each phase current is not zero. For example, a current transformer with a transformation ratio of 400/5 can convert the actual 400a current to 5a current.
