Abstract

PURPOSE:To obtain the value of insulation destructing voltage or the durable voltage characteristic at an optional area, by setting a needle electrode on the surface of an insulated electric wire and then applying the voltage between the electric wire and the needle electrode to measure the insulation destructing voltage at the area where the voltage is applied. CONSTITUTION:The measuring device for insulation destructing voltage consists of the needle electrode 1, insulated electric wire 2 to be measured, lead wires 3 and 4, jigs 5 and 6 and others. The figure 7 shows the movable load. When the load 7 is shifted left, the force of the electrode 1 to press the wire 2 is reduced. When the load 7 is shifted right, the force applied to the wire 2 is increased. Both the arm 8 and jig 9 support the electrode 1, and thus the electrode 1 can be set and removed on/from the surface of the wire 2. In such way, the destruction of insulation can be measured at an optional area of an insulated electric wire.
