<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for switching measurement mode (phase confirmation, insulation resistance measurement, and grounding) of a cable, which achieve cable phase confirmation, cable soundness confirmation and easiness of cable grounding work while securing operator's safety. <P>SOLUTION: The apparatus for switching measurement mode of a cable includes: first to third connection terminals 11 to 13 to which one ends of first to third cables are respectively connected; first and second resistors 17, 18 with different resistance values; and switching means 19. The switching means 19 grounds the first connection terminal 11 in the first mode, grounds the second and third connection terminals 12, 13 respectively through the first and second resistors 17, 18, sets the first to third connection terminals 11 to 13 to an opened state in the second mode, and grounds the first to third connection terminals 11 to 13 in the third mode. Since the switching means 19 switches between three circuit connection states matched with the first to third modes, cable phase confirmation, cable soundness confirmation and easiness of cable grounding work can be achieved while securing operator's safety. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
