Existen diferentes clases de resistencias, las cuales vamos a relacionar a continuaci\u00f3n:<\/p>\n

Puesta a Tierra<\/h1>\n

En las instalaciones de puesta a tierra se presentan diferentes resistencias:<\/p>\n

<\/p>\n

Resistencia espec\u00edfica de tierra<\/h2>\n

\u03c1E es la resistencia el\u00e9ctrica espec\u00edfica de la tierra. Se indica en \u03a9m y representa la resistencia de un cubo de tierra de 1 m de lado, entre dos planos opuestos de dicho cubo.<\/p>\n

Resistencia de propagaci\u00f3n<\/h2>\n

RA de una toma de tierra es la resistencia de la tierra entre la toma de tierra y la tierra de referencia. RA es pr\u00e1cticamente una resistencia efectiva (\u00f3hmica).<\/p>\n

Resistencia de choque de toma de tierra<\/h2>\n

Rst es la resistencia efectiva existente entre un punto de la instalaci\u00f3n de toma de tierra y la tierra de referencia al producirse el paso de la corriente de rayo.<\/p>\n
