LO-CTLS1 Flexible Rogowski Coil Current Sensor
Introduction to the Rogowski Coil The Rogowski coil is a specialized electrical device designed for non-invasively measuring alternating current (AC) and transient currents. Named after physicist Walter Rogowski, it features a flexible, air-cored helical winding, typically formed into a toroidal shape. Unlike traditional current transformers (CTs) that use magnetic cores, the Rogowski coil’s design allows it to be easily wrapped around a conductor without disconnecting the circuit, enhancing practicality in confined spaces.

>Product overview
Flexible Rogowski 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≥30cm) or irregular shape or narrow space between conductors (for example, when the traditional clamp current probe can't measure, the flexible Rogowski coil current sensor can be used to measure conveniently). Rogowski coils are renowned for their inherent advantages, including high linearity, wide frequency response, and immunity to magnetic saturation. Their non-intrusive design ensures ease of installation without the need for direct electrical contact or modification of the primary circuit.
