Abstract (en)
[origin: DE19613664A1] The force-loaded high-voltage lines (2) are interrupted electrically by a separator (3) which absorbs the forces in the lines. A current sensor arrangement (4) is electrically connected in parallel with the separator (3). The measuring signals are transmitted optically via a light guide (9) which is guided in a flexible insulator (6) at earth potential. The advantages afforded by the invention are a high level of safety with respect to earthquakes and good electrical isolation.
