Power Manager software:

Power Manager is a powerful platform for downloading, analyzing recorded data and creation of power quality test reports. Power Manager contains a package of functionalities needed for profound evaluation of power quality phenomena, data comparison and creation of complex test reports. It works in conjunction with Nieaf-Smitt new generation Power Quality Analyzers.  

Main features:

  • User friendly interface: wide range of quick buttons, possibility to customize the environment by dragging, docking and resizing the window tabs.
  • Structure: downloaded data is organized into Windows Explorer-like tree structure.
  • ‘Drag and drop’: downloaded data can be easily organized into multiple sites and sub-site locations
  • Data filtering: data in a structure can be grouped by quantity or by phase.
  • Views: depending on selected record type, different views are available.        
  • EN50160 analysis: automatic voltage quality analysis in compliance with custom or predefined EN50160 Power Quality criteria and quick report printing.
  • Chart zoom: chart can be zoomed depending on selected in a table value range.
  • On-line monitoring: when instrument is connected with PC, real-time observing of signals and parameters is possible via Power Manager while instrument is measuring / recording in the background.
  • Export of test results: test results can be exported to other programs (MS Excel, MS Word).
  • Reports: automatic generation of test reports from the selected views and data with attached graphs
