Why protect Transient overvoltages are voltage surges that can reach tens of kilovolts with a duration of the order of microseconds. This type of surge can have various different causes, including atmospheric lightning direc tly striking the ex ternal protection (lightning rod) on a building or transmission line or the associated induction of el e c tr o m a gn e tic f iel d s o n m e t al l ic conductors. It is also common for non-weather phenomena, such as transformer center switching or the switching off of motors or other inductive loads to cause voltage spikes in adjacent lines....

Transient voltage surges General operation and selection How a protector works. A surge protective device acts as a voltagecontrolled selector switch and is installed between the active conductors and earth in parallel to the equipment to be protected. When the network voltage is lower than the activation voltage, the protector acts as a high-impedance element, so that no current passes through it. On the other hand, when the network voltage exceeds the activation voltage, the protector acts as a near-zero impedance element, deriving the surge to earth and preventing it affecting the...

Power supply network configuration For the selection and application of the best possible protection device, it is essential to know in which electrical network it will be installed connected, since each model is designed for a different earthing system. These are the various configurations of the modules in the CPS family: Grid diagram Protection diagram 1 Ph; 3 W + G Split-phase Single-phase or Edison 4 conductors 3 Ph Y; 4 W + G 3 phase WYE 3 phases 5 conductors 3 Ph ∆; 4 W + G Highleg DELTA 3 phases 5 conductors 3 Ph ∆; 3 W + G 3 phase DELTA 3 phases DELTA “undergrounded” 4 conductors
