| Abstract: | The causes of the random fluctuation in the plinke of digit frequency measurement of the speed governer of a turbine and the harmful effects on the governing system are discussed in this paper.The measurs to restrict the random fluctuation and the methods of the accurate measurement of the frequency are also presented. These measures and methods are of practical value. An effective and practical method is also presented to test the statistic performance of the measuring devices of the speed governer with a microprocessor. |
