Power Quality Analysis Report

NOTE: This report is part of the Power Quality Performance Module. This Module requires a separate license.

Summary

The Power Quality Analysis Report shows power quality (PQ) summary information, such as breakdowns of PQ event types, impact, and location. It also includes information on disturbances (harmonics, unbalance, and so on) and power factor. Use this report to help you understand the power quality in your facility, reduce downtime, and increase equipment reliability and availability.

Details

Depending on the events and disturbances you select, the generated report provides data categorized as follows:

  • Power Quality Event Summary, consisting of Power Quality Events Breakdown, Power Quality Events Impact, and Power Quality Events Location.
    • Power Quality Events Breakdown shows the percent distribution of the events in a pie chart.
    • Power Quality Events Impact shows a percent distribution of the events with a likely impact and no impact in a pie chart.
    • Power Quality Events Location shows the distribution of the number of events in a bar chart with likely impact and no impact identified for each of the External, Internal, and Undetermined locations.
  • Power Quality Events — Details, consisting of events impact and events location for each detected event. and Disturbance Details for each detected disturbance.
    • Events Impact shows the number of each event type with a likely impact and no impact.
    • Events Location provides a distribution of the number of each event with a likely impact and no impact in External, Internal, and Undetermined locations.
  • Power Quality Disturbances — Details, consisting of a graphical representation of the distribution for each disturbance followed by a data table containing measurement and value details.
  • Power Factor — Details, consisting of additional information on power quality disturbances. The logged data represented in a trend chart is for each Incomer or main meter defined in the PowerQualityGroups.csv file. The table below the chart shows Active and Reactive energy data grouped by each power source meter. The red target line in the chart is set to 92 by default on the report template page.
