The transient recovery voltage (TRV) of the transformer limited fault (TLF) current interrupting condition has been investigated with several transformers by using current injection (CIJ) method. A transformer model for the TLF condition is treated as leakage impedance and a stray capacitance with an ideal transformer in a computation by EMTP. By using the frequency response analysis (FRA) measurement, the transformer constants were evaluated at high frequency regions. FRA measurement graphs showed that the leakage inductance value of the test transformers gradually decreases along with the frequency. From these results, frequency dependent transformer equivalent circu it was constructed. The frequency response of the model was good agreement with measurement.
