To cope with the high rate of increase of power demand in main industrialized districts in Japan, 550 kV transmission systems, covering the districts, have been reinforced, and most of the main power plants are directly connected to the 550 kV systems. Through 550/300 kV substations, the majority of power to the districts is supplied by 300 kV systems. To limit the excess short-circuit capacity in the 300 kV systems they trend to be reconstructed as, so called, Radial Networks. In radial networks with high short-circuit capacity and relatively small number of transmission lines connected to the sub-station bus-bars, the rate of rise of TRV can be far higer than standard values.<br>This paper analyzes the transient recovery voltages (TRV) in such extra high voltage radialnetworks in Japan, together with the relevant stresses to circuit-breakers during fault clearings. Future system conditions have also been introduced. As the typical rate of rise of the TRV values, more than twice of the today's standard ones are probable.
