- Ideally used with permanently installed Iris Power 80pF Epoxy Mica Capacitors (EMC)
- Remote inputs with 8 analog points proportional to operating conditions such as equipment temperature, voltage, current or power. These conditions are recorded for trending and analysis.
- The PDTracII 4208 uses superior automatic noise separation technology based on filtering and pulse shape analysis to reliably distinguishing partial discharges from electrical interference (noise) to prevent false alarms.
- In response to a PD alert, users can review the pulse height analysis plots, and the 24-window phase resolved PD plots using basic interpretation to confirm the cause of the alert
- The PDTracII 4208 can operate “stand alone” system with only periodic downloading of archived partial discharge data or it can be networked into the plant control system for remote data acquisition and analysis through USB, Ethernet or Modbus.
- An alert output using a dedicated relay can activate a remote indicator of high partial discharge alert conditions. The alert output may also be connected to a plant monitoring system.
