Different conversion principles and control methods of Split Core Current Transducers

In the process of operation, the Split Core Current Transducer converts a large current into a small current of the same frequency in phase to facilitate measurement or isolation. In operation, according to different transformation principles, the device generally has a Hall effect, magnetic Pass-through, electromagnetic induction, Rogowski coil (electromagnetic induction principle and ampere loop law), shunt (ohm theorem) these five technologies.

The current clamp of the Split Core Current Transducer processes an air gap in the iron core to place the Hall element, and uses the Hall element to measure the magnetic induction intensity in the air gap. According to different control methods, the current sensor has two types of open loop and closed loop, and the open loop Both DC and AC can be measured with closed-loop Hall-type current clamps.

Split Core Current Transducer Direct-measuring open-loop Hall type uses a Hall element with better linearity. The output voltage of the Hall element is proportional to the current to be measured. The open-loop Hall-type transformer has a far-reaching CTS series.www.ctsensorducer.com
