<p>PURPOSE:To execute a charging test even in a narrow space by installing airtightly a bushing to an apparatus case, and omitting a testing case. CONSTITUTION:A bushing 9 which is provided on the other end of a lead wire 10 having a charging part 8 in one end is installed airtightly to an apparatus case 7 of a both end apparatus direct-coupled cable line 6, so that a tip part 12 of its conductor leading-out electrode is positioned in the case 7. In such a state, a charging test is executed by applying a test voltage to the charging part 8 of the lead wire 10. In this case, since the bushing 9 is installed airtightly to the case 7, a testing case can be emitted, therefore, a space for executing the test can be reduced.</p> |
