Signalization device for use in over-voltage protection device for signalization of flash current in e.g. off-shore wind energy system, has monitoring device provided for detecting interruption of conductors, which exhibit same large length

The device (1) has conductors (2, 3) arranged in a parallel and electrical conducting manner. The conductors exhibit different, large ohmic resistors and inductors. A monitoring device detects interruption of the conductors. The conductors exhibit same large length and different large cross sections. The conductors are designed as conductor paths of conductor boards. The monitoring device is attached to the conductors. The conductors are impacted with spring forces, and the monitoring device comprises a unit i.e. lamp, for remote signalization of interruption of the conductors. Independent claims are also included for the following: (1) a method for signalization of the peak current (2) an over-voltage protection device comprising an over-voltage protection element.
