Royal Caribbean Cruise Lines needed a reliable system to continuously thermally monitor key 11kV electrical switchgear on the propulsion systems of its Voyager Class liners.
QHi Infrared has solved a problem for Royal Caribbean Cruise Lines (RCCL), which needed a reliable system to continuously thermally monitor key 11kV electrical switchgear on the propulsion systems of its Voyager Class (world's current largest) liners.
The ExerTherm system from QHi, specifically designed to provide continuous 24/7 thermal monitoring, for key components inside electrical switchgear enclosures, was successfully installed earlier this year.
Eric Schreiber, Chief Electrical Superintendent for RCCL stated: "The ExerTherm system solved our problem, and helps us avoid potentially expensive consequences from unplanned power outages on our key propulsion system switchgear".
ExerTherm uses small, plastic, noncontact IR sensors which require no power.
These are placed inside the switchgear enclosure to directly and continuously monitor any key component.
The system can identify potential problems at an early stage of development via ongoing trend analysis.
It also provides two individual alarms per sensor, which activate if temperatures exceed customer defined levels.
This is a significant technology step forward from thermographic scanning which can only provide periodic inspection (and thus not trend analysis), and only of those components immediately adjacent to the external switchgear panel surface.
Although thermal imaging provides a valuable inspection tool for many other electrical system components, it has quite severe limitations when it comes to switchgear enclosures.
ExerTherm is also successfully installed in numerous blue chip organisations in financial services, telecommunications, IT, computer data centres, media and large-scale manufacturing.
