【Abstract】 The work principle of the optical fiber voltage transformer with capacitor is analyzed, and the circumstance of the study and the test for COVT under 220kV introduced. The analysis and the tests prove that COVT combines the traditional CVT and optical fiber, which shows good immunity from electromagnetic interference, excellent insulation and high measuring accuracy. The measuring accuracy for COVT under 220kV has already shown 0.3%. With software correction, the accuracy may be even higher.更多还原
