The LEM ART Series Split Core Rogowski Coil is an accurate, reliable, and easy-to-install energy sensor designed for smart city applications. It provides galvanic separation between the primary and secondary circuits for the electronic measurement of AC current. Featuring patented Perfect Loop Technology, it significantly reduces positioning errors and errors due to external conductors. This flexible, thin, and lightweight solution offers quick, non-intrusive setup and is adaptable for a wide range of cable diameters, making it ideal for MV/LV substations, power metering, building sub-metering, power quality monitoring, fault detection, RTUs, and PMUs.
