A Rogowski coil is an electrical device for measuring alternating current(AC) or high-speed current pulses. There is no metal (iron) core. The winding density, the diameter of the coil and the rigidity of the winding are critical for preserving immunity to external fields and low sensitivity to the positioning of the measured conductor.

Advantage of Rogowski Coil Flexible
1. open-ended and flexible, allowing it to be wrapped around a live conductor without disturbing it. 2. high-current Rogowski coil to be calibrated using much smaller reference currents 3. No danger of opening the secondary winding. 4. Lower construction costs 5. Temperature compensation is simple. 6. smaller than an equivalent rating current transformer.
