Abstract

The invention relates to an overvoltage protection device with monitoring and communication functions, in particular for the information and process industries, having at least one surge arrester with a self-diagnostics unit and a wireless and/or wired standard interface for data transmission. According to the invention, an additional module is provided to detect the behaviour and/or the properties of a connected electrical energy source, wherein a bidirectional exchange of data and commands to and between a higher-level control system and among multiple overvoltage protection devices takes place and parametrisation of lower-level terminals to be protected can be realised via the standard interface.
