Continuous vs. Piecewise Hysterisis Model of a Current Transformer

a quicker method to implement the standard CT model in circuit simulation is introduced. Using the introduced non-linear magnetizing equation with adjustable parameters, the CT's saturation curve can be instantaneously reproduced avoiding the process of defining linear segments and determining how many are necessary. An actual CT is modeled using the suggested method and results from excitation transients are compared with the traditional piecewise linear model as well as with experimental results for verification.
