operation or normal frequency condition. under emergency condition such as lowering of frequency or synchronizing of large machines a very fast action is needed‚ which may not be possible for a human operator. Thus there is a need of autosynchroniser in a power station or in an industrial establishment where generator are employed. This paper describes a microprocessor based set up for synchronizing a three phase alternator to a busbar. Also existing methods of synchronization are mentioned
