Smart Cable Fault Location Diagnosis System

Repairing underground cable lines might be challenging due to a lack of a proper system for tracking the precise location of cable faults. Repairing wires of a defective cable becomes extremely difficult in the case of an underground fault because there is no way to locate the exact location of the fault. A microcontroller is used in this research study to investigate underground cable fault distance locators. It employs a straightforward interpretation of Ohm's law; the voltage drop might change depending on the length of the fault in the cable since the current varies. A group of resistors is used to represent the cable's length in kilometers. A DC voltage is put into one end of the cable, and the defect was identified using an analog to voltage converter when the voltage changed. The LCD displays the location of the defect as it interacts with the microcontroller that does the necessary calculations. Overhead cables were developed in recent years, but they are now laid as underground cables, which is superior to the earlier technique because the underground cables are not impacted by inclement weather like storms, snow, heavy rain, or pollution.
