Power quality analyzer and fault recorder – multimess


The power quality analyzer and fault recorder multimess F144-PQ for low, medium and high voltage networks is the central component of a system that can be used to solve all measurement tasks in electrical networks. Detect possible malfunctions before they lead to a loss of production or defects in plant components. The multimess F144-PQ measures and monitors the network quality. It can be used as a power quality interface according to network quality standards, such as IEC61000-2-2 / EN50160 or to check technical connection guidelines, such as DIN VDE AR 4110 and DIN VDE 4120.
