Description
Smart grid solution with a scalable measurement system. Line quality evaluation with modular load flow information for line level 7 (low voltage). The respective current measurement values are processed with the so-called Current Link modules. The individual Current Link technology and its sensors (Rogowski) are provide scalable networks using signal loop via coaxial cables. Thus the installation expenditure is reduced to an absolute minimum and a professional cable routing is ensured. In addition, this measuring system for determining the power quality is extremely cost-efficient and on top metrologically certified. The scalable measuring instrument almost combines the range of transducer according to IEC60688, Power metering and monitoring according to IEC61557-12 and Power quality instruments according to IEC62586-1.
