Abstract
This Paper represents that to compute the distance of the underground and overhead transmission cable from fault location to the base station using Arduino.
In this paper, a smart technology-based fault detection and location system was used to adequately and accurately indicate and locate the exact spot where fault had occurred.
This will ensure a shorter response time for technical crew to rectify these faults and thus help save transformers and other electrical equipment from damage and disasters.
For underground cables (UC) fault detection, we use the concept of ohm’s law. UC has many types and it has different resistance that depends upon the length of the cable.
The low DC voltage is applied at the feeder end through series resistor (cable lines), the current would be vary depending upon the location of fault in the cable. When, there is short circuit (Line to ground), the voltage across series resistor change accordingly, which is the fed to the inbuilt ADC of Arduino to develop precise digital data for display in meters.
In this paper the set of resistors representing cable length (in meters) and fault is created by the set of suitable at every instant in meters, to verify the accuracy .The fault is displayed on Liquid Crystal Display (LCD) interfaced to Arduino.
For overhead cables (OC) fault detection, when the open circuit and short circuit fault occur, our sensing device i.e. relay sense the fault and send information to the microcontroller.
The microcontroller senses that command and display on Liquid Crystal Display (LCD). The system uses an Arduino board, Liquid Crystal Display (LCD), Relay, Resistors, voltage supply etc.
Arduino system detects the faults, analyses and classifies these faults and then, determines the fault distance. Then, the fault informates and classifies these faults and then, determines the fault distance. Then, the fault information is transmitted to the control room.
