Critical protection

25 September 2015

Condition monitoring specialist Sensonic has delivered the first tranche of machinery protection systems to the Barakah Nuclear Power Plant project in the UAE.

Following a two year design and production phase, the equipment delivery, made up of 92 (ninety two) Sentry G3 4-channel protection modules and over 300 channels of vibration analysis across three cabinets, is currently undergoing commissioning as part of the Unit 1 construction phase.

The instrumentation will monitor and protect 45 machines, the balance of plant equipment for Unit 1, consisting of various fans, pumps and chillers in support of the steam turbine. The fully programmable Sentry G3 equipment is utilised to monitor bearing and shaft vibration in addition to thrust wear and speed.

The 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 Mimic’s in combination with offline analysis of historical trends.
