Análisis de la influencia de los sistemas de puesta a tierra en la eficiencia de instalaciones eléctricas de baja tensión residenciales e industriales.

[EN]Nowadays, global society is more aware of electrical energy’s risks than never before, and electrical safety has turned a priority when a new installation is designed. So, a great protection to an unwanted electric hazard is required, being specially careful with indirect contacts. If a circuit has an insulation failure and an indirect contact is produced, there is risk of an accidental electrocution, risk that must be avoided by making a good choice of the grounding methodology and properly coordinating the electrical protections in the installation. In order to minimize that risk, a study of low voltage industrial and residential installation’s grounding methodologies is introduced, analyzing the tree grounding methodologies internationally accepted (TT, TN, IT). In addition, two real examples are solved (using a computer-aided engineering software), confirming the results of the theoretical study.
