JESUS PIŅA, yes it has a low frequency pulse although on the scope it looks like white noise because of all the other frequencies moving through the ground. When lightning discharges somewhere on the globe it sends a ripple through the earth, like tossing a stone in the water. When you single pulse a tesla coil it rings at its natural frequency until the energy has dissipated. There are lightning discharges at any moment of any day somewhere on our world ringing the planet at its natural frequency.
Even though the ground is a good conductor at low frequencies there is a considerable amount of resistance. When we put ground rods in we want to offer these currents an easy path, they will follow the path of the least resistance, preferably through our circuits. Since the voltage is very low with currents that can be quite high at times we want to use heavy cable - very low resistance wire and space the grounds 30ft or more positioned magnetic north/south. The north rod should penetrate the earth much deeper than the south rod.
Once your grounds are in, use the simple detector I described. If the LED flashes then you have current flowing on the line. I posted a couple circuits sometime back in this thread that can function with this type of low voltage current. ( post#275 page10 )
