TRA05

TRA05 Three-phase 1A Rogowski coil current sensor

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. TRA05 three-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
• Protection relays
• Power Quality

Benefits of Rogowski Coils

Rogowski Coil Current Transformers are designed for precision AC current measurement in power metering or general energy monitoring applications. The flexible Rogowski Coil provides a versatile solution for crowded electrical panels where rigid current transformers simply cannot fit. Much like split core current transformers, the user-friendly locking connector opens for easy integration into existing panels without disconnecting wires. Available in a variety of sizes to fit any application.
