Underground cable fault detection using arduino circuit diagram.

I am working on a project called arduino based underground cable fault detection system. The objective of this project is to determine the distance of underground cable fault from base station in kilometers using an arduino board. In this project we created faults manually. It is constructed using a constant current source of 100mamps.

Arduino based underground cable fault detection circuit. In the event of short circuit line to earth fault the voltage accordingly. Programs uploaded in arduino uno kit to detect faults from the underground cables. Cable has many types.

The underground cable system is a common practice followed in many urban areas. The system detects a voltage drop when the circuit is short circuited on each phase and displays the exact location of the fault in kilometres else it should display no fault. So it is necessary to know the exact location of faults in the underground cables. Detection of fault location in underground cable using arduino 2.

Main component of the underground cable fault detection circuit is low value resistance measurement. In power system generation to distribution has more long cable are used and now we used underground cable. The circuit consists of a power supply 4 line display arduino and resistance measurement circuit to induce faults manually in the kit fault switches are used about 12 fault switches are used which are arranged in three rows with each row having 4 switches the 3 rows represent the 3 phases namely r y and b the fault switches have 2 positions no fault position nf and fault position f main component of the underground cable fault detection circuit is low value resistance measurement. We make use of this voltage across change resistors to detect the fault.

When the underground cable is used to distribution in the urban area sometime fault occurs is an underground cable that time finding fault. In this paper to detect a fault in an underground cable is still a challenging task in power system. While a fault occurs for some reason at that time the repairing process related to that particular cable is difficult due to not knowing the exact location of the cable fault. The circuit is consists of 4 line display arduino and resistance measurement circuit.

In order to detect an variation short circuit fault open circuit fault this project provides accuracy in determining the exact location of fault when a low dc voltage is applied at the feeder end through a. Whatever the fault is the voltage of the cable has the tendency to change abruptly whenever a fault occurs.
