The flexible Rogowski coil current sensor is designed for precise measurement of alternating current, achieving electrical isolation between the primary and secondary circuits. Through advanced winding techniques, it significantly reduces positional errors of the measured conductor within the aperture, it improves the anti-interference ability of flexible Rogowski coils against external magnetic fields.
