Underground Cable Fault Detection Using Arduino Circuit Diagram

The circuit is consists of 4 line display arduino and resistance measurement circuit.

Underground cable fault detection using arduino circuit diagram.

The objective of this project is to determine the distance of underground cable fault from base station in kilometers using an arduino board. 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. Lcd display which dis plays the faults in kilometre. Programs uploaded in arduino uno kit to detect faults from the underground cables.

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. In this paper to detect a fault in an underground cable is still a challenging task in power system. 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. When the underground cable is used to distribution in the urban area sometime fault occurs is an underground cable that time finding fault.

It is constructed using a constant current source of 100mamps. I am working on a project called arduino based underground cable fault detection system. Flow of presentation introduction to project underground cable v s overhead cables faults in underground cables methods for the detection of faults introduction to the circuit working of the circuit different circuit components. Arduino based underground cable fault detection circuit.

When a fault occur in the underground cables we can find out faults through arduino controller kit. Underground cable fault detection. In this project we created faults manually. Detection of fault location in underground cable using arduino 2.

So it is necessary to know the exact location of faults in the underground cables. 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 underground cable system is a common practice followed in many urban areas. Main component of the underground cable fault detection circuit is low value resistance measurement.

In the event of short circuit line to earth fault the voltage accordingly. We make use of this voltage across change resistors to detect the fault.
