The crucial point is that these transients are transmitted via power and data lines. Overvoltage protection modules with strap varistors from EPCOS safeguard electrical equipment reliably from these transients. Also, temporary overvoltages may occur in addition to the pulsed transients due to lightning and switching operations: they are caused by phenomena such as switching operations, load rejections, resonances, and shorts-to-ground.
