By accurately determining the length of time for which electromechanical and solid state protection relays can reliably remain in operation on the GB Transmission system, the financial elements linked to the various replacement options can be deferred to a later date – allowing greater flexibility in the asset investment process.
To ascertain through detailed scientific analysis and testing, the period of time for which certain models of electromechanical and solid state protection relays can remain in operation on the GB Transmission System.

To determine the effects (if any) that the operational lifetime of the electromechanical and solid state protection relays has had on the reliability and anticipated design life of the units.
