The respective measured current values are processed with the so-called current Link Module. The individual current links and their sensors (Rogowski) are networked in a scalable manner via coaxial lines by means of link technology using a signal loop. This reduces installation effort to an absolute minimum and ensures proper cable routing. Furthermore, the measuring system for determining power quality is extremely cost-efficient – and metrologically certified to boot. The scalable measuring instrument thus combines transducers in accordance with IEC60688, power metering and monitoring in accordance with IEC61557-12 and power quality instruments in accordance with IEC62586-1.
