The objective of condition monitoring is to measure and analyse the operational data of a machine in such a way that deterioration can be detected before it becomes unacceptable. Condition monitor of gas turbines can help to reduce maintenance costs by increasing the time between overhauls and reducing the risk of secondary damage. The Paper discusses the specification and design of a mini-computer based system installed at Hastings Power Station to monitor the condition of two 55 MW gas turbo-alternators, each powered by four Rolls-Royce Avon gas generators. These turbo-alternators are used mainly for peak lopping and run for short periods at high power. The detailed design of the condition monitoring system reflects this pattern of use, but the principles and analytical methods are equally applicable to gas turbines used for marine propulsion.
