FAQ

Technical insights into flexible inductor coils and current measurement.

🛡️ 1. Why does the coil feature double shielding for AC current measurement?

Double shielding significantly reduces external electromagnetic interference (EMI), ensuring high signal-to-noise ratios and accurate data acquisition, especially in high-frequency power environments.

⚡ 2. Can the measurable current range be adjusted after installation?

The coil itself is linear up to 10KA; however, the actual measurement range is typically determined by the integrator and display equipment, which can be calibrated to specific customer needs.

🌀 3. Does this flexible coil experience magnetic saturation like traditional CTs?

No. Since the Rogowski coil uses a non-magnetic core (air core), it does not saturate, allowing for high-accuracy measurement of both very small and extremely large currents without distortion.
