Abstract

La disposicion tiene un conductor que ocasionalmente está puesto a tierra y provee senales e incluye un dispositivo sensor subterráneo y una unidad deacondicionamiento y control de senales en la superficie donde el sensor utiliza las líneas deenergí a principales para llevar las senales del sensor. Se proveeun esquema de puesta a tierra de alta resistencia conectable, de modo que en el caso de una falla de tierra de arco o situacion similar la disposicion puedaponerse a tierrainmediatamente, co mpensando así los efectos de la falla de tierra de arco y provee seguridad al personal y proteccion a los equiposeléctricos. Cuando la conexion de tierra de alta resistencia no se utiliza, las senales mencionadas de los sensoresson llevadas fácilmen te por los conductoresde energía.
