要約(日本語): To study transient recovery voltage (TRV) at transformer limited fault (TLF) interrupting condition, EMTP transformer equivalent circuit was constructed using the impedance values which were calculated from frequency response analysis (FRA). The purpose of the study is to understand clearly the TRV of TLF condition. The study results with 4kVA and 300kVA transformers showed the amplitude factors (A.F) are about 1.4. In this paper the simulation result of TRV with 50 MVA transformer will be presented.
