A brief introduction to surge protection Is surge protection worthwhile? Is surge protection worthwhile? You can rely on luck or take precautions The priority you give to surge protection depends on your willingness to take risks! Perhaps you think ”it’ll never happen to me”. You won‘t have lost anything, but you will also have gained little, if nothing at all, and you run the risk of a surge overvoltage at any time. However, if you wish to be on the safe side, simply make sure you include surge protection as part of your corporate strategy. Such an investment will not only assure you of operational...

A brief introduction to surge protection Is surge protection worthwhile? Disaster from inside your premises Wherever electricity is used, it must also be switched on and off. The physical processes involved in a switching operation cause many surge overvoltages than those from the sky. Added to this are overvoltages caused by electrostatic discharges or faulty switching operations. These overvoltages are nowhere near as high as those of lightning, but as they are generated directly in the lines, they are also directly in the system and place a stress on the insulation. An item for use with 230...
