ZCT411 zero phase sequence current transformer reliable factory

Electrical Specification

(Customized is available)

Common features of zero current transformers and current transformers:

Both zero current transformers and current sensor work according to the principle of electromagnetic induction, but in different working states.

Current transformer:

The primary coil of an ordinary current transformer only passes through one phase conductor of the measured line, the current in the primary coil is the load current of such phase, and the secondary current is the corresponding ratio of the primary current.

Zero phase current transformer:

The primary coil of the zero current transformer passes through the three-phase conductor of the measured circuit. Under normal conditions, since the vector sum of the three-phase currents is zero, no magnetic flux will be generated in the iron core, so there will be no induced current in the secondary coil.
