Description

Flexible Roche coil is obtained by cable puncture 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. The tie-up installation is convenient for construction, especially for large current measurement. Due to its flexible characteristics, it can be used to measure the conductor current with large size (such as conductor diameter ≥3 m) or irregular shape or very narrow space between conductors (for example, when the traditional clamp current probe can not be measured, the flexible Roche coil current sensor can be easily measured). The joint has temporary type and long-term type, the former is plug type, used for portable instrument or temporary current measurement, used for long-term current measurement on line. Easy to install without damaging the conductor.
