Abstract
Un sistema para determinar la impedancia de tierra de un sistema de conducto incluye una funda conductora y un resistor de valor conocido. La funda conductora se configura para rodear una porción de un conductor alojado dentro de un sistema de conducto. Se produce un acoplamiento capacitivo entre la funda y el conductor para establecer una fuente de tensión. El resistor se acopla eléctricamente entre la fuente de tensión y un componente metálico del sistema de conducto, y se lee una caída de tensión a través del resistor para determinar el estado de la impedancia de tierra del sistema de conducto.
