Generating more power from turbo-alternators is of increasing importance in today’s competitive generation market.
Some of the ways this can be achieved are by plant modifications or enabling each unit to generate for longer periods between maintenance. Plant maintenance based on need, rather than preventative maintenance can prove effective at keeping the plant operational, whilst saving significant sums of money. In order to adopt this strategy, it is necessary to be able to determine the condition of the plant in a cost-effective and non-invasive manner. There are a number of ways of doing this, but one of the most effective for rotating plant is vibration analysis.
