Verify the Fault Alarms (Power Quality Events) and Generate Reports

You can verify the fault alarms and generate reports by performing the following steps:

  1. Install PQDiff.
    a. It is recommended to use the free software PQDiffractor for visualization and analysis of PQDIF files. In the operating system, you can associate the PQDIF file types with PQDiffractor so that the software automatically opens the files on double-clicking them.
    NOTE: You can download PQDiffractor from the following location: http://www.pqview.com/pqdiffractor/.
    b. Run the PQDiffractorSetup.exe and follow the steps in the Wizard, leaving the default settings, to install the PQDiffractor application.
    c. Select the Accessories program folder to tell the setup where to add the program icon.
    d. Create a shortcut to the PQDiffractor.exe in the folder C:\Program Files (x86)\PQDiffractor.
    e. Use the measurement files uploaded to: [Installation Drive]:\[Installation Folder]\[Project Name]\data\IEC61850\DR\CNS node name\OtherFiles and Fault files that are uploaded to: [Installation Drive]:\[Installation Folder]\[Project Name]\data\IEC61850\DR\CNS node name\FaultFiles.
  1. Verify the Fault event in the Event List.
    a. To generate a fault event, the PQM device is connected and has the following settings in the Client and in the Object Model Creator tab. In this device, the Value.info.FaultNumber property automatically displays in the Selected Properties section of the Object Model Creator tab, when you click the Discover objects button. In order to display the Object Model Creator tab, you must select the IEC61850 network or the device connection object below the network in the System Browser. For example, turn the potentiometer to reduce the 24 V supply voltage. This simulates a voltage dip and should evoke a fault event. Compared against the 90% voltage dip threshold, a fault should occur at anything under 21.6 volts.
    b. Observe that a Fault alarm appears in the Summary bar and event list.
    c. Identify the fault number and the event information. You should see the event with cause set as Power Quality fault observe the Fault Number property in the Extended Operation pane. This number is the running total of power quality events.
    d. Acknowledge the event to set the event back to normal and ready it to be closed.
  1. Generate measurement and fault reports to analyze the incident.
