PROBLEM TO BE SOLVED: To provide an attachment/detachment method of a high-voltage hot line ammeter capable of performing a measuring work to a high-voltage hot line at a reduced cost with an increased efficiency.;SOLUTION: This attachment/detachment method of a high-voltage hot line ammeter is for attaching and detaching, to and from the high-voltage hot line, a clamp type ammeter comprising an openable and closable clamp part mounted so as to surround the high-voltage hot line in a closed state and biased toward the closed state by spring force and a fixing means for fixing the clamp part in the closed state to measure current based on a magnetic field induced in the clamp part by the current carried to the high-voltage hot line. The process for attaching the clamp type ammeter comprises steps of pulling the other end of a ring member having one end preliminarily hooked on the clamp part while holding the clamp type ammeter by a predetermined holding tool and a predetermined operation tool; arranging the clamp part so as to surround the high-voltage hot line and stopping the pulling operation; and operating the fixing means so as to fix the clamp part in the closed state.;COPYRIGHT: (C)2005,JPO&NCIPI
