Abstract (en)

[origin: WO2016050907A2] The invention relates to an overvoltage protection device with a monitoring function (1), comprising a parallel connection of two current branches (A, B), wherein the first current branch (A) comprises a first overvoltage protection device (Ü1) and a second overvoltage protection device (Ü2) which are connected in series, the second current branch (B) comprises a third device (E3) and a fourth device (E4) which are connected in series. The first overvoltage device (Ü1) and the third device (E3) comprise, when in operation, a first common voltage potential (P1), and the second overvoltage device (Ü2) and the fourth device (E4) comprises, when in operation, a second common voltage potential (P2). A first measuring tap (M1) is provided between the first overvoltage protection device (Ü1) and the second overvoltage protection device (Ü2) and a second measuring tap (M2) is arranged between the third device (E3) and the fourth device (E4). A signal (S1, S2) is derived from the voltage between the first measuring tap (M1) and the second measuring tap (M2), said signal providing a status indication with respect to the first overvoltage protection device (Ü1) and the second overvoltage protection device (Ü2).
