Lightning and surge protection Lightning and surge protection 1. Introduction – Legislative The use of modern sophisticated equipment, consumer electronics and control systems places high demands on their electromagnetic compatibility. Modern electronic control systems provided with circuits with a very high integration level are becoming more and more sensitive to electromagnetic disturbance and overvoltage. The installation of surge protections according to effective legal standards will reduce the danger of their being damaged to a minimum. Technical designs are defined by standards...

I Lightning and surge protection 2. Connection of protections inTN,TT and IT systems Principle of connection of surge 3. Principles of positioning and wiring of surge arresters and lightning current arresters Surge arresters and lightning current arresters cannot be installed in the distribution system at random. You must be aware of the fact that protection should be placed at the closest proximity to the input feed cable in order to minimize the inductive loop area, see fig. 1. Fig. I - Examples of device positioning in the distribution system. overhead, PEN (PE) down overhead, PEN (PE)...
