Resumen

The use of electrical energy in low voltage networks is exposed to overvo ltages from atmospheric discharges that affect equipment and people, so in an electrical system, surge protection devices SPD (Surge Protective Device) are generally installed. in bypass configuration between line and ground conductors to reduce detrimental effects. The objective of the research is to determine the optimal procedures for the installation of surge protection devices in low voltage networks to avoid dete rioration in protection equipment and avoid personal accidents through the combination, lo cation of protection devices, double voltage effect, the connection and coordination of SPD. Procedure that will allow continuous operation through the overvoltage protec tion device that activates and discharges the lightning current to ground that will short-circuit the electrical circuit with the link from the well to ground by connecting the equipotential grounding with the installations exposed by a short time, limiting the duration of the overvoltage.
