Abstract (in Japanese) (See Japanese page) 
(in English) The brush gear reliability for turbine generator is more and more important in recent days. In this research, in case of steel ring, peculiar brush V-I characteristic has been found. It is clarified that figure of the peculiar brush V-I characteristic is “saturated” while the figure for copper ring is almost “linear”.
In this paper R-U characteristics is investigated according to Holm's manner. As a result of R-U characteristic measurement, fritting like characteristics have been found and the fritting like characteristic implies the reason why brush current sharing unbalance is smaller in case of steel ring, than in case of copper ring.
