Industrial Surge Protection Devices: 5 Key Applications by Sector
Industrial surge protection devices are not interchangeable across industries. An oil and gas facility with explosive atmospheres, a water treatment plant with dispersed outdoor pumps, a substation, a regulated pharmaceutical line and a VFD-dense machine shop each face different surge sources and installation constraints. This guide maps SPD selection to five industrial sectors, identifying the main surge sources in each, the critical equipment at risk, and the recommended device type and installation point. It covers lightning exposure on remote wellheads and pump stations, switching transients from large motors and variable frequency drives, and the vulnerability of PLCs, sensors and SCADA systems on the plant floor. A sector matrix summarises device type and installation location at a glance, giving specifiers and contractors a fast reference for matching industrial surge protection devices to the real risk profile of each site.
