Abstract
This paper reports a CCVT calibration effort for harmonic voltage measurement purpose. A set of frequency response studies are conducted on two types of 345-kV Coupling Capacitor Voltage Transformers (CCVT). The Electro-Magnetic Transients Program (EMTP) is used to develop the CCVT model and conduct this digital simulation. The accuracy of the CCVT frequency response study result is verified through comparison of the EMTP digital simulation results with those obtained from field measurements. The comparison results demonstrate that the developed model can accurately predict CCVT frequency response, and can provide good adjustment values for harmonic measurement purpose.
