View graphs and generate reports with Fluke Power Quality Log software

With its easy-to-use interface, the included Power Quality Log software assists you with logger setup, enables you to verify actual measurement values quickly using the online function, and downloads data from the logger to a connected PC operating on standard Windows® operating systems. You can view the logged data in graphical and tabular form, export it to a spreadsheet, or generate a professional report with the Report Writer function.

  • For root cause analysis, different measurements such as flicker, voltage and THD can be shown in the same time plot, helping to quickly identify the cause of a disturbance.
  • Statistical summaries like EN50160 and DISDIP table provide a quick, comprehensive summary. The EN50160 overview display provides a simple display of 8 power quality parameters on one dashboard, according to the latest international power quality standard.
  • Statistical analysis of Voltage and Current harmonics over a given time period. Red bar graphs indicate issues with the grid. Other colors are warnings for pontential future issues.  Harmonics can be presented also as time plots.
The Fluke 1745 Three Phase Power Quality Logger is an advanced IP50 power quality logger with real-time LCD and five hours UPS for technicians who troubleshoot and analyze power quality issues. Capable of simultaneously logging up to 500 power parameters for up to 85 days and monitoring for events, this allows you to analyze power quality in detail and to correlate intermittent events, helping to identify the root cause of disturbances.
The included PQ Log software quickly assesses the quality of power at the service entrance, substation, or at the load, according to the latest EN50160 standard.
The Fluke 1745 Three Phase Power Quality Logger can not only measure the common power parameters but it also measures voltage and current harmonics, interharmonics, mains signaling, unbalance, and frequency.
Apart from the Fluke 1745, the Fluke 1740 series includes two other power quality loggers: Fluke 1743 & Fluke 1743.
  • The Fluke 1743 is capable of measuring most common power parameters but cannot measure voltage and current harmonics, interharmonics, mains signaling, unbalance or frequency.
  • The Fluke 1744 is more similar to the 1743 and is a better solution if you need to measure what the 1743 is incapable of measuring.
Applications:
  • Disturbance analysis - Uncover root cause of equipment malfunction for later mitigation and predictive maintenance
  • Quality of service compliance - Validate incoming power quality at the service entrance
  • Power quality studies - Assess baseline power quality to validate compatibility with critical systems before installation
  • Load studies - Verify electrical system capacity before adding loads
  • Energy and power quality assessment - Validate performance of facility improvements by quantifying energy consumption, power factor, and general power quality before and after improvements
