Underground Cable Fault Detection

Abstract

Nowadays underground cables are used over than overhead lines in urban areas. Locating the fault in the underground (UG) cable is tedious and there is a probability of damaging the insulation while digging the cable. The proposed system offers easy and smart fault detection by automating it using a ARDUINO controller. The basic concept of Ohm’s law is applied at the feeder end though a series resistor. In case of short circuit of LL or LLG or LG the current flowing in the faulty sections will vary depending on the length of the line. This paper aims at estimating the location of fault distance and intimating the personal through SMS (short message service). The data are send to a dedicated website together with on board LCD display by using a GSM module and Internet of Things (IoT).
