Sensonics begins condition monitoring system commissioning at UAE new-build nuclear power plant08 November 2018

Condition monitoring supplier Sensonics has delivered the final tranche of machinery protection systems to the Barakah Nuclear Power Plant project in the UAE.

Following what it described as a five year design and manufacturing phase, final commissioning has begun of nearly 400 Sentry G3 4-channel protection modules and more than 1,200 channels of vibration analysis across 12 cabinets.

Sensonics says that the instrumentation will monitor and protect 180 machines, pumps, fans and chillers supporting operations at the four-reactor plant -- so-called 'balance of plant' systems -- being built by Korean Electric Power Corporation.

The Sentry G3 equipment is utilised to monitor bearing and shaft vibration in addition to thrust wear and speed. Installed specification includes dual redundant power supplies in each rack with redundant ethernet communications to the main plant systems for trending of overall vibration levels and the reporting of alarms. A condition monitoring package is also integrated with the G3 equipment to provide real time analysis of the vibration signals. All data is stored on a local server which provides live machine mimicry, in combination with offline analysis of historical trends, Sensonics reports.
