Roche Coil Transformer (flexible Opening Transformer)

Product Overview

Flexible roche coil current sensor is used to measure AC current,especially high current. Because of its flexible characteristics, it can be used to measure the conductor current with large size (such as conductor diameter ≥ 3M) or irregular shape or narrow space between conductors (for example,when the traditional clamp current probe can not measure, the flexible Rogowski coil current sensor can be used to measure conveniently). The former is plug-in type, which is used for temporary measurement of portable instrument or current, and for on-line long-time measurement of current. It is easy to install without damaging the conductor.
