MARINETRACII

Partial Discharge Monitoring (Marine Application)

Continuous partial discharge monitoring for motors, small generators, metal enclosed switchgear and isolated phase bus (IPB) applications typically between 4kV and 28kV in Marine applications.

Data can be collected on up to 4 machines through 80pF Iris Power Epoxy Mica Capacitors to identify severity of partial discharge so that you have the information needed to avoid catastrophic failures, extend the life your asset and reduce the risk of unplanned outages.

  • Robust continuous monitor tested to withstand harsh plant conditions. Modular hardware and easy connections to facilitate field repairs and upgrades
  • Data collected by the Iris Power MarineTracII monitor is compatible with the existing TGA/PDA technology. Users with existing sensor installations can commission the system without a machine outage.
  • Continuously collecting on 3 sensitivity ranges – a User Specified range, a range that Automatically adjusts to current partial discharge levels, and a range suitable for evaluating high partial discharge conditions (Alert Range).
  • The Alert testing range ensures minimal intervention by maintenance personnel. In response to a partial discharge 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. Alert levels are pre-set based on the Iris Power database of over 272,000 test results.
  • Alert Output is a dedicated relay fitted within the monitor enclosure that can activate a remote indicator of high partial discharge alert conditions,. The alert conditions are configurable through the operating software. The alert output may be connected to a plant monitoring system.
  • The Iris Power MarineTracII monitor is equipped with ambient sensor input modules to enhance data gathering for trending and analysis. Using an optional sensor, ambient temperature and ambient humidity can be recorded along with the PD data readings.
  • USB memory stick port for downloading stored data without a laptop computer.
  • Qualitrol-Iris Power has extensive experience with continuous online partial discharge monitoring. Over 2,000 continuous online partial discharge monitors have been installed.
  • Networking with an Ethernet port for remote diagnostics, downloading, configuration with Iris Power software.
  • Modbus-over-Ethernet protocol is included for interfacing to third party systems. This allows the Iris Power MarineTracII to input operational parameters to be stored along with the PD readings, as well as output partial discharge summary data to third party applications.
  • The Iris Power MarineTracII system will take partial discharge sensor inputs from up to four (4) motors or generators provided the terminal boxes of all four machines are within 20m of the Iris Power MarineTracII monitor.
  • Remote I/O over Ethernet with four analog inputs proportional to operating conditions such as stator winding temperature, voltage, current, or power. These conditions are recorded for trending and analysis.
  • Remote I/O over Ethernet with six analog outputs proportional to the level of PD activity (+Qm and –Qm). This is applicable in situations where the user is interested in having the real-time PD activity acquired by their DCS or control system.
