Cathodic Protection specialists BAC Corrosion Control Ltd (BAC) have recently completed a contract to design, manufacture and supply 40 SCADA controlled Transformer Rectifier (TR) units for a prestigious project in the Kingdom of Saudi Arabia (KSA).
SCADA (supervisory control and data acquisition) is a computer system for gathering and analysing real time data. SCADA systems gather information, such as operating levels of Cathodic Protection equipment, transfers the information back to a central site, alerting the home station in the form of an alarm if faults arise, carrying out necessary analysis and control, and displaying the information in a logical and organised fashion. SCADA systems can be relatively simple, or more complex, such as this system where 40 Transformer Rectifier units are all monitored and controlled by a single centralised computer.
The system is being supplied to Cumberland Cathodic Protection Ltd, and will ultimately be sent to the Royal Commission in Yanbu, KSA for the protection of steel reinforcement in concrete structures.
The new TRs contain new Switch Mode Power Supplies which have been designed and developed by BAC along with DC Surge Suppressors and 1GΩ Impedance Buffers, all manufactured by BAC at their facility in Telford, UK.
The project is worth in the region of £75,000 for BAC and it is anticipated that it will be the start of new things to come with the introduction of new technology into the already successful Transformer Rectifier operations within BAC.
