Verification of a computational model of a voltage transformer for the study of ferroresonance processes in distribution electrical networks

Methodology for parameterization of voltage transformer model was developed. Verification the is carried out by comparing nameplate data with results computer calculations. The magnetization branch parameters are determined values, such as current and residual transformer’s magnetic circuit. In conclusion error angular estimated in terms amplitude values root-mean-square curve type «NOL-SECH-20». Calculations were help EMTP-RV software.
