Split Core Current Transformer KCT

split core current transformer are usually installed on current intensive power lines or equipment, and output the measured current signals to users for monitor measurement or protection.

Introduce:

HEYI and ASCT brand of KCT type split core current transformer have been specifically designed to be small CT and easy to open and yet maintain the accuracy required for kwh meters. The benefit of a split core current transformer is that it can be placed into position easily and without disturbing or disconnecting the main cables it is monitoring. The KCT type of current transformers has two insulated terminal covers for connecting the S1 and S2 cables which lock down over the terminal screws fully insulating the connections. This makes it ideal to use Autometers cable hamesses which are colour coded and individually numbered on each conductor ensuring simple and easy connection from the current transformer to the electricity meter.

Features:

• The structure of the self-locking, safe, easy to install, portable.

• Wide range of sizes to accommodate all the existing installations.

• Isolated plastic case recognized according to UL94-V0.

• Wires plugs,Audio plugs,Power plugs and so on five kinds of plugs.

Applications:

• Current measurement, monitoring and piotection for electrical wiring and equipment.

• Current and power measurement for electric motors, lighting, air compressor, heating and ventilation system,air-condition equipment and automation-control system.

• Current, power and energy monitoring device.

• Relay protection device.

• Charging pile

• Data center

Current transformer (CT) is a widely used power measurement sensor in power systems, which is used to measure the current in high voltage (AC) circuits. Its main function is to convert a large current into a small current to facilitate measurement and protection of the circuit. It can provide the function of isolating and protecting the circuit

Before installing a CT, the measurement is performed directly on the circuit, but this often leads to circuit overload and damage, as well as potential safety hazards. To avoid this situation, CT is used to monitor the current.

There are many different types of current transformers, including split core current transformer, closed type current transformer, pole type current transformer, and window  type CTs, which have their respective advantages, disadvantages, and applicable conditions. However, they all work on the same principle

The winding of the CT is wrapped in an iron core and can be accessed by installing clips or perforations. When there is current flowing through the circuit, the current will generate electromagnetic induction inside the CT winding. This will cause a secondary current to be generated at the CT output, and the magnitude of the secondary current is proportional to the input current.

When using CT, close attention needs to be paid to accuracy and inductance. The accuracy of a CT depends on its scale and phase error. Inductance is also one of the factors that need to be considered, because CT not only consumes a certain amount of electrical power, but also produces magnetic interference.
