Current Transformer

Split core current transformers are a series of miniaturized openable products designed based on the improvement of current instrument and equipment software processing capabilities. Due to the increase in current monitoring equipment, there is a need for an open-type current transformer that is easy to install and compact.   

Split Current Transformers 5 to 600 amps of alternating current through the center conductor. The split core design allows for non-contact current measurement via magnetic field induction without the need to take the main wire offline and disconnect when installing the CT. This approach enables safer, simpler and portable current measurements.

Products can be customised Clamp-on current transformers with Permalloy cores for high-precision measurements are stable and reliable for long-term operation.

Products can be customised Designed with advanced technology and engineering expertise, our harvesting energy CT products ensure accurate monitoring and extraction of current.

Products can be customised The harvesting energy current transformers can be installed outdoors directly exposed, measuring the current and converting the conductor current into electrical energy through electromagnetic induction, providing energy for other components.

Products can be customised The harvesting energy current transformers are suitable for use in buried cables and utilise the principle of electromagnetic induction, whereby the magnetic field generated by the current in the conductor is induced through the toroidal coil to produce electrical energy.

Products can be customised Our current transformers measure and extract electrical energy to power accessories such as sensors.

Measures AC current flow to electric motors,lighting, air condition equipment, etc. Compatible with HVAC temperature control, power management, building automation systems.

Our current sensors are split-core current transformers characterized by high accuracy and low phase shift.  They are precisely designed for the electronic measurement of AC waveform current, ensuring galvanic separation between the primary circuit (power) and the secondary circuit (measurement). Covering a range from 0 A to 125 A, these current transformers are primarily intended for mounting on the primary circuit.

The split core current transformer is designed based on the principle of quick and easy use. The split structure design of the transformer does not need to disconnect the tested cable or busbar. It can perform safe and simple current testing.

The open-type current transformer is easy to install. There is no need to remove the primary busbar. It can also be operated with power without affecting the customer's normal power consumption. It can be used in conjunction with relay protection, measurement and metering devices.

Products can be customised The harvesting energy current transformer can be directly mounted in the outdoor exposed, widely used in current measurement, and can generate electrical energy through the wire current induction.

Products can be customised The split harvesting energy current transformer is easy to install and replace, and can provide power to other components.

Products can be customised Current transformers for current measurement and inductive power supply, customised with silicon steel or permalloy cores.

Products can be customised The self-powered current transformers can be installed outdoors directly exposed, measuring the current and converting the conductor current into electrical energy through electromagnetic induction, providing energy for other components.

Hemei Electronics is a domestic manufacturer specializing in the research, design and production of power supply current transformers, split core current transformers, clamp-type current transformers, high-precision current transformers and miniature voltage transformers. Measures AC current from 1A to 5000A with outputs of 0.333V, mA, 1A and 5A.

The split core current transformer are designed for fast and easy installation.The CTs are ideal for installation on existing electrical cables by clamping on the conductor.This method permits a safer,easy and portable current measurement.An internal precision burden resistor across the secondary winding of the CT provides a safe low voltage output and permits safe opening of the secondary.

Products can be customised Clamp current transformer current-carrying wire position correlation variance is small, anti-interference ability is strong, such as it will be connected to the high accuracy of the power meter, ammeter, phasor meter, can be more accurate on-site inspection, both safe and can improve work efficiency.

Can be customised for various ratios, high frequency, precision and other special requirements.

Split-core current transformers are designed for quick and easy installation.The CT's have an internal precision load resistor on the secondary winding that provides a safe, low voltage output and allows the secondary winding to be safely opened.
