【Abstract】 This paper describes the measuring principle of optical fiber electrical field transducer used for condition monitor of electric power system, and gives the structure of the measuring system. The practical measurement for the steady-state alternating current electric field is taken. The test results show that the measuring system has excellent linearity with about 0.3%, nearly no hysteresis, less than 0.5% relative error and good stability, and satisfies the requirements of electric power system and electrical apparatuses.更多还原
