They provide continuous data on system performance, helping detect anomalies, track trends, and ensure that all components are functioning within optimal parameters. This capability is essential in industries such as energy, manufacturing, and transportation, where early detection of issues can prevent downtime and improve system reliability.
Metering Systems
In metering systems, current transducers ensure highly accurate readings for energy consumption and load monitoring. By converting primary current signals into measurable voltage or current outputs, they offer precise data for billing, system performance evaluation, and regulatory compliance. Whether in residential, commercial, or industrial settings, these transmitters enhance the effectiveness of metering systems, providing transparency and reliability in energy management.
Control Systems
Current transducers are integral to control systems, where they provide critical feedback to optimize performance. By continuously measuring the current, these devices help regulate processes, ensuring stability and efficiency. In automated systems, they enable fast response to current fluctuations, adjusting operations in real-time to prevent equipment damage or energy waste. From motor control to process automation, current transducers play a pivotal role in maintaining control and ensuring operational excellence.
Types of Current Transducers
DC Current Transducers (DCCT)
DC current transducers are designed specifically for direct current measurement. Unlike inductive methods that only work with changing (AC) signals, DCCTs use magnetic field sensing technologies such as Hall-effect, flux‑gate, or magneto‑resistive probes to detect both static and dynamic DC currents with excellent isolation and precision.
Hall‑effect sensors detect the magnetic field produced by current via the Hall effect.
Flux‑gate and magneto‑resistive probes provide higher accuracy and stability, especially in low‑noise or precision applications.
Open‑Loop Transducers
The Open‑Loop Transducers use a Hall sensor placed in the magnetic core’s air gap to directly detect the magnetic field produced by the current. The sensor’s voltage is amplified to produce an output proportional to current. Open‑loop designs are simpler, more cost‑effective, and consume less power, making them suitable for general measurement tasks that do not require ultra‑high precision.
Closed‑Loop Transducers
In closed‑loop designs, a feedback coil actively nulls the magnetic field inside the core by generating an opposing flux. This “zero‑flux” condition stabilizes the measurement and dramatically improves accuracy, linearity, and temperature stability. Closed‑loop transducers are preferred in precision applications, though they are more complex and often more costly than open‑loop types.
AC Current Transducers (CT)
AC current transducers are based on Faraday’s Law of Induction, which states that a changing magnetic field induces a proportional signal in a sensing winding. They are ideal for measuring alternating current in systems like power grids, generators, and electrical substations. In typical AC CTs, the primary conductor passes through a magnetic core, and the induced secondary signal (often via a winding) is scaled and isolated for measurement. Many AC CT designs also use shunt resistors to convert secondary current into a measurable voltage output.
