Abstract: A new method for CT saturation correction is presented that is based on an on-line estimation of the CT magnetizing inductance. The approach adopted is based on numerical solution of the differential equation, which describes the saturated current transformer. The correction procedure proposed has been tested with EMTP-ATP signals proving to be an effective tool for primary current reconstruction.
