Prerequisites

The following is required to set up the DDD Indicators application:

• PME must be installed and commissioned.
• Power monitoring devices with DDD functionality must be installed in your electrical network in those locations where you want to monitor for voltage disturbances. The devices must be connected to PME and must be communicating. The following devices are compatible with this application:
  • ION9000
  • PM8000
  • ION7650 (v350 and higher)
  • ION7550 (v350 and higher)
  • ION7400
  • ION8650A/B (v407 and higher)
  • ION8800A/B (v362 and higher)
  • 9410 series
  • 9810 series
  • ACCESS 9610
• The internal clock of the monitoring devices must be time synchronized. The standard synchronization (± 1s) between the PME server and the monitoring devices is good enough. High accuracy (± 1ms) time synchronization (for example, GPS, IRIG-B, or PTP) can also be used, but is not needed for this application.
• Power quality event detection for Sag/Swell and Transients must be enabled in the power monitoring devices for which you want to show the disturbance indicators in the one-line diagram.
• You need a one-line diagram for each electrical network that you want to include in this application. For information on how to create diagrams in PME, see Creating and customizing a user diagram.
