Abstract
【解決手段】容器内に配置されたエネルギー蓄積装置22の直列電力接続体24に対して検出器2bが連結され、直列接続エネルギー蓄積装置から導出された試験信号の状態変化を検出し、絶縁層27における破損箇所の存在を検出する。検出器2bは、直列に接続されたエネルギー蓄積装置22の対向する端部のエネルギー蓄積装置22に隣接して夫々連結された一対のタップラインを備え、タップラインの各々と容器との間にはスイッチにより選択的接続が提供される。タップライン上において、選択された端部エネルギー蓄積装置の電圧と等しい電圧の基準状態から、選択された対向端部エネルギー蓄積装置の電圧を実質的に超える電圧より非基準状態が検出される。
