High-voltage Current Transformer

Overview of High-Voltage Current Transformer

High-voltage Current Transformer is an electrical device that works in a high-voltage environment. Its primary function is to convert current so low-voltage and low-current instruments can indirectly measure high-voltage and high-current parameters. This device is an integral part of the power system and is mainly used to monitor and protect the power system.

High voltage current transformers typically consist of primary windings, secondary windings, and magnetic cores. The primary winding has fewer turns and is connected in series in the tested circuit to induce the measured current; The secondary winding has a large number of turns and is connected to measuring instruments or control systems to transmit the induced current to the measuring equipment. The function of the magnetic core is to enhance the magnetic flux of the transformer and improve the induction accuracy.

Functional Principle of High-Voltage Current Transformer

Current Transformer: The primary function of a voltage Current Transformer is to reduce the current in high-voltage and high-current circuits in a particular proportion for easy measurement and monitoring. This is achieved through the use of the law of electromagnetic induction. When a current passes through the rudimentary winding, resulting in an induced electromotive force in the secondary winding, reducing and transmitting the current.

Isolation function: The voltage Current Transformer achieves circuit isolation through the insulation distance between the primary and secondary windings, preventing direct intrusion of high voltage into measuring instruments, meters, and protective devices and protecting the safety of equipment and personnel.

Measurement and protection: By reducing the current in high voltage and high current circuits in a particular proportion, the voltage Current Transformer provides measurable low voltage and low current signals for measuring instruments, meters, and protection devices for current measurement, monitoring, and protection.

Protective device: The High-voltage Current Transformer usually has a protective device inside to prevent damage to the equipment caused by overload and short circuits. These protective devices can promptly cut off the power supply in case of abnormal situations, protecting the equipment from damage.
