<p><P>PROBLEM TO BE SOLVED: To provide a partial discharge detector capable of knowing not only a point that causes a partial discharge but also the quantity of partial discharge on that point. <P>SOLUTION: The electric charge processing unit 22 calculates the quantity of attenuation of partial discharge between the position of a partial discharge sensor 1 and a partial discharging position calculated by the position processing unit 21 according to the attenuation characteristic data 25 of partial discharge in a preset metallic container 10 and calculates the quantity of partial discharge made on the partial discharging position from the attenuation quantity and the waveform data S1 of the partial discharge sensor 1. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
