UNDERGROUND CABLE FAULT DETECTION SYSTEM

Electrical and Electronics Engineering

The main objective of this project is to detect the faults and abnormalities occurring in underground cables using an Arduino. The basic idea behind the working of this project is ohms’s law .At the feeder end ,when a DC voltage is applied, based on the location of fault in the cable ,the value of current also changes. So in case of a short circuit fault like L-G or L-L fault the change in voltage value measured across the resistor is then fed to the in-built ADC of the Arduino. This value is processed by the Arduino and the fault is calculated in terms of distance from the base station. This value is sent to the LCD interfaced to the Arduino board and it displays exact location of the fault from the base station in kilometers for all the three phases. This project is arranged with a set of resistors which represent the length of the cable. At every known kilometer fault switches are placed to induce faults manually. Finally the fault distance can be determined.
