Single-phase flexible Rogowski coil without integrator

T Series Rogowski Coil Current Sensor

The flexible Rogowski coil current sensor is used for precise measurement of alternating current, enabling accurate measurement between the primary and secondary circuits.
The electrical isolation, achieved through precision winding techniques, significantly reduces positional errors of the measured conductor within the aperture and enhances the flexible Rogowski coil's immunity to external magnetic interference.
