Lightning Surge Protection Devices Can Help In Protecting Electronic Devices

Lightning can cause major damage to building structures. When lightning strikes indirectly power surges can occur in power cables or transmission links. Lightning Surge Protection Devices are critical for large scale industries, the need for surge protection devices can depend on numerous factors. Such as the exposure of a building to lightning transients, the sensitivity and value of the equipment, the location and exposure level of the installation and the equipment used within the installation and whether this equipment could generate transients.
