Abstract: The primary point of this venture is to identify the deficiencies and variations from the norm happening in underground cables utilizing a microcontroller. The essential thought behind the working of this venture is ohm’s law. At the feeder conclusion, when a DC voltage is connected, based on the area of blame in the cable, the esteem of current too changes. So in case of a brief circuit blame like L-G or L-L blame the alter in voltage esteem measured over the resistor is at that point encouraged to the in-built ADC of the microcontroller. This esteem is handled by the microcontroller and the blame is calculated in terms of separate from the base station. This esteem is sent to the LCD interfaces to the microcontroller and it shows correct area of the blame from the base station in kilometers for all the three stages. This extend is orchestrated with a set of resistors which speak to the length of the cable. At each known kilometer blame switches are put to actuate issues physically. At the blame separate can be determined
