Abstract

The objective of this research paper is to determine the distance of underground 3 phase power cable fault from base station in kilometers by using PIC microcontroller & GSM. This project uses the simple concept of ohm's law & Voltage divider rule. When short circuit occurs in a 3 phase power cable, voltage changes based on the length of fault happened in a cable, since the current varies. Here, 1 KΩ resistors are used to represent the cable for R, Y and B [1]. The fault is detected by detecting the change in voltage using an ADC and a PIC microcontroller. These ADC & PIC Microcontroller are used to make the required calculations for fault detection and once the calculation done, the fault distance will be display on the LCD screen. SIM 800 - GSM module is used to send the information via AT Commands.
