This thesis aims to establish a measure prepared by the cable break (the underground) to take advantage of the power cord is damaged or broken rails, wires or pipes wires buried in the ground. Without digging the light rail lines to determine the damage to waste time. The authors of the measure, thus creating a cable break (the underground) to assist in finding a cable break more easily by using the principles in the input signal in the UHF frequency 27MHz into wiring problems. And hence the detector Check out the line of wires embedded in the soil. Find the missing or the signal is weak, the LED intensity LED lamps are light and show that the measured signals to the fullest, but if the LED flashing, it indicates that the signal is weak, and if the LED does not display at all or not. then show that the Broken or damaged wires in the point itself.
