<p><P>PROBLEM TO BE SOLVED: To safely and easily perform fitting or removing work of a clamping-type ammeter with respect to a high voltage hot line by one operator with only one holder. <P>SOLUTION: In the holder of the clamping-type ammeter, the clamping-type ammeter having a clamping part energized to a state where it is closed by spring force and measuring current based on a magnetic field induced by the clamping part with current flowing in the high voltage hot line surrounded by the clamping part in the closed state is fitted or removed to or from the high voltage hot line. The holder is provided with an insulating container where a face on a side where the clamping-type ammeter is stored is opened, a spacer in which a gap which is not less than a diameter of the high voltage hot line is caused by inserting it into the clamping part and which is removed by depressing it on the high voltage hot line, and with an insulating operation rod supporting the insulating container. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
