Wylfa is located on the north coast of Anglesey and has two Magnox design nuclear reactors and four turbine generators. The station supplies 23 million kilowatt hours of electricity, enough to meet the needs of two cities the size of Liverpool and Manchester put together.
A PROTOR system has been installed and running Wylfa since 1998. The system monitors the four main steam turbine generators and also eight gas circulators, four for each of the two reactors. The system provides important vibration trends for these critical items of plant for both local and remote analysis.
The new contract is to replace the existing PROTOR-3 Remote Monitoring Data Analysis Systems (RMDAS) with new PROTOR-4 P4700 units. A total of eight P4700 units will be supplied, one for each main turbine and one to monitor a pair of Gas Circulators. The flexibility of the P4700 in handling multiple machines with individual tachometer or phase reference signals is ideally suited to this requirement.
