| Abstract: | An equivalent circuit model of capacitor voltage transformer(CVT) and its system is established.Taking a 35 kV CVT for example,the causes of the over current on the primary side of CVT are analyzed.The Bode-diagram of CVT and its system is derived to reflect the distribution of resonance points.According to the magnetization curve of nonlinear inductor of CVT's intermediate transformer and quick saturation damper,a simulation model is derived by the corresponding voltage-ampere characteristics.ATP-EMTP elec... |
