A lightning strike doesn’t have to hit your building to cause catastrophic damage. Even one 20 to 50 metres away can inject thousands of volts into the ground — surging through buried cabling, data lines, and metal structures. This phenomenon is called Earth Potential Rise (EPR) — or Ground Potential Rise (GPR) — and it’s one of the least understood yet most destructive causes of electronic failure. In this video, we explain how EPR happens, why it’s so dangerous, and how THOR Smart Series Network Protectors instantly divert this invisible energy surge safely to earth — protecting your modems, cameras, servers, and control systems before damage occurs. You’ll Learn: • What causes Earth Potential Rise (EPR) • How EPR surges can destroy data and network systems • Why proper earthing is essential • How THOR Smart Series protection works in real-world installations THOR Smart Series. High-Speed Network Surge Protection.
