The EGB governor with 16PC-2.5V diesel engines takes the largest proportion of EDG type in Korean N.P.P. We were investigated operating characteristic changing of EGB governor according to Maintenance interval. As a result, the change of speed setting did not change until 3 years after maintenance but the maximum change was 31 rpm after 6 years. Other changes in operating characteristics were slight change. The change of speed setting is changed the speeder spring tension and worn flyweight toe, that caused by the vibration due to various performance tests of the EDG like rapid load change and fast start.
