TRA03

TRA03 1A Rogowski coil current sensor/CT

The combination of Rogowski coil and integrator can achieve 90° phase shift compensation and frequency compensation, making the output of the Rogowski coil in phase with the primary current, independent of frequency, and suitable for more application scenarios. TRA03 single-phase current integrator with Rogowski coil is a replacement for current transformer (CT), which is light, flexible and easy to install. It can output industrial standard 0-30mA, 0-50mA, 0-1A instantaneous current like CT secondary, which is proportional to the measured primary current.

Certified CE and RoHSIII compliant
DIN rail mounting
Small size

Applications:

Arc furnace
Power Quality
Power monitoring and control
Applicable to electronic energy meter

Features and Benefits of Rogowski Coils

Air-core design: Unlike traditional iron-core current transformers, Rogowski coils have no magnetic core and will not saturate, so they can measure extremely high currents without distortion.
Flexibility: Most Rogowski coils are designed as flexible coils that can be unwound without disconnecting the wires, making installation simple and non-invasive, and lightweight and low-cost to ship.
High bandwidth: Currents containing high-frequency components or rapidly changing currents, such as those in lightning strikes or switching transients, can be accurately measured.
