<p><P>PROBLEM TO BE SOLVED: To provide a space-saving, inexpensive, and new device of diagnosing insulation for an electric apparatus including electric power apparatus tank including a metal container and an inner metal body applying a high-voltage into the metal container. <P>SOLUTION: The device of diagnosing insulation for an electric apparatus includes an adapter ring provided at the outer circumference of an electric power apparatus tank including a metal container and an inner metal body applying a high-voltage into the metal container. The adapter ring includes: a detection electrode provided in contact with the electric power apparatus tank; a signal electrode extending upward from the detection electrode; a ground electrode provided via an insulating member with the detection electrode and provided without electric contact with the signal electrode; and a through-member penetrating through the insulating member, for partially connecting the detection electrode with the ground electrode. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
