multimess D9-PQ

Energy measuring devices
multimess D9 PQ CLASS A 1

The multimess D9-PQ network analyzer helps you to analyse the cause of faults in electrical systems and machines. The permanent monitoring and control of the power quality by the measuring device means that potential faults can be detected as early as possible.

The multimess D9-PQ power quality analyzer and fault recorder for low and medium-voltage grids can be used for all measurement tasks in electrical grids. It can be used both as a power quality interface in accordance with power quality standards EN 50160 and as a measuring device for all physically defined measured variables in three-phase networks. It also supplies the consumption values required for energy data management.
