Considering the risk of blackout, Kyushu electric power company has studied about power system restoration at blackout start. Power system at blackout start is so small that over voltage which does not rise in normal power system is able to rise, because of transient phenomena and saturation of transformer which are caused by voltage application. Power system transformers should be applied its voltage as low as possible, ideally from zero, to prevent over-voltage problem. This paper reports field test results of voltage application by a voltage building-up procedure to a 500kV-1000MVA power system transformer through a transmission line.
