【Abstract】 This paper describes the theory and design of a new method for detecting power system harmonics on line,especially introduces the design of the method using RMS (root - meat - square) of harmonics amount as triger,the synchronous sampling circuits used for following the changes of power system frequency, and the passive sensor applying electric -magnetic coupling isolative method. At last,the result detected in actual power system arc given also.更多还原
