As the CURRENT enters the SOIL, a VOLTAGE GRADIENT (slope) is created on the soil抯 surface. The AFRAME is then plugged into the Receiver and it is used to sense voltage potentials along the cable path. The AFRAME has two probe tips, one is marked RED and the other is GREEN.?? The goal here is to determine when the RED and GREEN tips senses a NULL , a condition where the voltage potentials at the RED and GREEN tips are the same or zero).?? Once NULL is achieved, the center of the AFRAME will then represent the location of the FAULT (position 2).
