By Loop Type

Closed-loop Type Leads Owing to Their Higher Acceleration and Efficiency

Based on loop type, the market is majorly classified into open-loop and closed-loop.

The closed-loop segment dominated global current transducer market share. These transducers are widely preferred as they offer higher accuracy, noise immunity, and superior stability compared to open-loop current transducers. The enhanced accuracy and stability of the closed-loop is provided by the feedback loop that actively adjusts the secondary current to maintain a net-zero magnetic field at the sensing element and to reduce the errors caused by temperature fluctuations or environmental factors. For instance, the closed-loop current transducers offered by VACUUMSCHMELZE have the highest accuracy of 0.4% to 0.7%, with no temperature drift over the full temperature scale, low rise time, and a frequency range DC to 200 kHz. One of the key features of the closed-loop current transducer is the presence of a negative feedback loop, due to which the output signal of the sensor is compensated and calibrated with the input signal via a negative feedback mechanism. The negative feedback mechanism eliminates the error and drift, offering accurate and reliable measurements of power systems.

The benefit of the closed-loop current transducer is the lack of eddy currents and higher bandwidth. The output can be modeled as a current source with the current proportional to the primary current in a ratio determined by the secondary winding count. The closed-loop current transducers offer easy scalability and can quickly respond to changes in the measured current, which facilitates real-time monitoring of the current.

Open-loop current transducers measure current by detecting the magnetic field generated by the current and converting it into a proportional voltage or current output. They are commonly used in applications requiring current measurement with electrical isolation and are known for their simplicity and cost-effectiveness.
