The OFLS series Rogowski Coil is used for electronic measurement of AC current. The error due to the position of the measured conductor within the aperture and the error due to the proximity of the external conductor are greatly reduced using magnetic shielding techniques.
It has the advantages of fast response, small volume, small power consumption, frequency response width, anti-interference, lightning wave and shock wave protection.
