Power Quality Analyzer Marsen-PQP


Marsen-PQP is a power quality recorder and analyzer.


  • Measurement and monitoring of power quality parameters specified in IEC 61000-4-30 and IEC 61000-4-7 standards with further transfer of measurement results to a PC (power quality test reports according to EN 50160)
  • Measurement and monitoring of basic power quality parameters (PQP)
  • Measurement and monitoring of basic electrical network parameters

Field of application:

  • In power quality monitoring and control systems: permanent recording of power quality parameters and events on every cycle (can be installed at electrical substations of any voltage rating)
  • Monitoring of power consumption characteristics and power related parameter at “power-to-consumer” distribution points
