The monitoring kit will be beneficial for reactive maintenance. It could potentially help to carry out planned maintenance in a cost beneficial, risk managed and outage controlled manner. It should also raise confidence in new technology. Monitoring applied at appropriate times gives engineers more knowledge and information of the asset and enables longer lead times and clear assessment of management decisions. Using data currently held, as well as new data, it will allow enhanced performance and maximum efficiency. In effect it’s the drive towards a cost effective, optimum timing device to enable National Grid to move towards condition/risk base maintenance.
