要約(日本語): To study the transient recover voltage (TRV) characteristics at transformer limited fault (TLF) condition diode interruption experiment have been performed. In TLF condition frequency and attenuation of oscillation are mostly influenced by the leakage inductance and stray capacitance of transformer. Base on the previous study results, it was tried to understand the notion of TRV frequency and amplitude factor (AF) by connecting the extra capacitors at the test transformer. The results show TRV frequency and AF are related to the capacitance which connected to the transformer. These will be reported in this paper.
