The Influence of a Constant-Sign Current on the Magnetization Processes in Three-Phase Power Transformers
Keywords:
power transformer, magnetization, magnetic core saturation, constant-sign current, hysteresis, mathematical modeling
Abstract
The article presents the results of an investigation aimed at determining the influence of currents containing constant-sign components flowing through the windings of power transformers on the transients triggered by short-circuit faults and routine switching operations in the electric power system. The investigations of magnetization processes under the conditions of constant-sign currents were carried out using an analysis model in the EMTP-RV software environment developed by PowerSys, France. The model was verified by confirming the transformer nameplate data and based on full-scale tests carried out on the TLS-25/6 three-phase power transformer. The power transformer voltage-time curve of magnetization by a constant-sign current has been determined.
