<P>PROBLEM TO BE SOLVED: To provide a base for insulation resistance measurement of an insulation shoe, capable of measuring the insulation resistance of the insulation shoe without wetting an upper part of the insulation shoe with water, and an insulation resistance measurement device using the base for insulation resistance measurement. <P>SOLUTION: A fixing plate 14 is provided with a column 15 and a support plate 16 is provided on an upper part of the column 15. Then, a lower sponge material 17 is installed between the fixing plate 14 and the support plate 16, and an upper sponge material 18 is installed on an upper surface of the support plate. Then, water 22 is injected to a level slightly lower than the level of the support plate inside a container 13. In the state, when an insulation shoe 21 is mounted on the upper sponge material 18 and pressurized, since the entire sole 21a of the insulation shoe 21 is brought into contact with the water, by applying a voltage between an upper part 21b of the insulation shoe 21 and the container 13 and measuring a current that flows at the time, the insulation resistance of the insulation shoe 21 can be highly accurately measured. Also, infiltration of the water inside the insulation shoe 21 can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
