技術設備生產商和系統集成商都希望在有雷電的情況下也能夠無故障地運行。該類系統的故障和毀壞會帶來無窮后患。通過一個內容廣泛的防雷方案可以達到這個目標。除了建筑物防雷系統外，還需要有其他電氣電子設備的過壓防護措施。重要的是要考慮到所有產生過壓的原因。根據對過壓防護設備及其安裝部位的要求和任務，將它們分成雷電避雷器、電涌避雷器和組合避雷器。

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.

為了保護信息技術設備的輸入和輸出端設備,防止其被過壓損毀，也要使用電涌避雷器。其作用就是疏導和限制信息設備系統中出現的過壓,使其不再對設備構成威脅。這些就決定了要為信息系統中的設備選取合適的保護裝置。威瑯公司提供的Wietam產品系列為電信和信號處理網絡中的過壓防護設備。

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
