RISK OF ELECTRICAL SURGES Lightning and surge protection Electrical and electronic equipment is indispensable in the daily activities of today’s businesses and individuals. Such devices are connected to the electricity grid, often exchanging data and signals through communication lines and are usually sensitive to disturbances. These interconnecting networks provide a propagation path for overvoltages. Protection against lightning and overvoltages not only ensures the safety of people, goods and equipment, but also ensures continuity of installation services and meet criteria of energy efficiency....

Protection parameters according to IEC 61643-11 Iimp When selecting an SPD, several points must be considered: • Network topology: TNS, TNC, TT, IT, PV and No of conductors. • Nominal voltage rating (Un) of the supply. Impulse current Peak current with 10/350μs waveform which the protection device can withstand without reaching end of life. Imax Maximum discharge current Peak current with 8/20μs waveform which the protection device can withstand without reaching end of life. In Nominal current Peak current in 8/20μs waveform the protection device can withstand 20 times without reaching end of...

Protection system of coordinated stages: Type 1, 2 and 3 SPDs The SPDs of a surge protection system must be able to withstand the discharged current and provide a Ures level (residual voltage) lower than the Ue peak voltage that the equipment can withstand. Most of the times it is not possible to achieve this with just one SPD, especially because the intensity of the surge is not known, and because of the induction of overvoltages when conductors exceed 10m. The optimal system of protection is the 3-STEP approach, in which successive stages are combined in the performance of high discharge capacity devices...
