Product Description

 

 
Specification

Principle: Zero-sequence current transformer uses the principle of electromagnetic induction to convert the zero-sequence current in a three-phase circuit into a low-voltage signal. It consists of two parts, one is the core and the other is the winding, which is realized by the interaction of the core and the winding.

Structure: Zero-sequence current transformer usually consists of core, winding and housing, supported by insulating material and insulating structure inside. It can be a single-phase or three-phase current transformer.

Features: Zero sequence current transformer has the characteristics of compact structure, reliable work, high accuracy and strong anti-interference ability, which can transform the zero sequence current in the power system into a set of small currents suitable for measurement, so that the zero sequence current in the circuit can be measured accurately according to the requirements.

Application: Zero sequence current transformers are widely used in power systems, mainly for detecting grounding faults in power systems. In the power system ground fault occurs, the system will produce a large amount of zero sequence current, through the measurement of zero sequence current can be found in time to make the corresponding protective measures.

Note: In the installation and use of zero sequence current transformer, attention should be paid to maintain a good state of insulation, and regular testing and calibration.
