Abstract :
This paper reports the modeling on dielectric response for power transformer condition assessment. A model (a numerical tool) is implemented by C++ code based on dielectric theory. The model can calculate return voltage and polarization/depolarization currents. It can also calculate the maximum return voltage to generate spectrum data. Through the modeling, the parameters which contribute to the dielectric response in the real measurement can be seen much more clearly. A good numerical model is indispensable to remove the uncertainty and to accurately interpret the measurement results. The model can help us quantitatively analyze the measurement results from dielectric responses of oil paper insulation.
