技术设备生产商和系统集成商都希望在有雷电的情况下也能够无故障地运行。该类系统的故障和毁坏会带来无穷后患。通过一个内容广泛的防雷方案可以达到这个目标。除了建筑物防雷系统外，还需要有其他电气电子设备的过压防护措施。重要的是要考虑到所有产生过压的原因。根据对过压防护设备及其安装部位的要求和任务，将它们分成雷电避雷器、电涌避雷器和组合避雷器。
Owners of technical manufacturing plants and information systems desire an interference-free operation, even in thunderstorms. The zone concept for lightning protection enables planners, builders and owners to plan, implement and monitor protective measures. Not only for electrical systems of the building will be needed over voltage protection for electric device.Corresponding to the requirements and tasks overvoltage protection devices are faced with in their installation location, they are divided into lightning arresters, surge arresters and combined.

为了保护信息技术设备的输入和输出端设备,防止其被过压损毁，也要使用电涌避雷器。其作用就是疏导和限制信息设备系统中出现的过压,使其不再对设备构成威胁。这些就决定了要为信息系统中的设备选取合适的保护装置。威琅公司提供的Wietam产品系列为电信和信号处理网络中的过压防护设备。
Surge arresters are used to protect input and output modules in IT systems from being destroyed. Their task is to divert and limit any over voltage that occurs in the IT system so that it no longer presents a danger to the modules. Another factor is that the signals must not be influenced in an undue manner. These largely determine the selection of suitable protective devices
