Underground Cable Fault Detection Using Arduino Circuit Diagram

In the event of short circuit line to earth fault the voltage accordingly.

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. When a fault occur in the underground cables we can find out faults through arduino controller kit. It is constructed using a constant current source of 100mamps. Underground cable fault detection.

So it is necessary to know the exact location of faults in the underground cables. Programs uploaded in arduino uno kit to detect faults from the underground cables. Cable has many types. In this project we created faults manually.

The circuit is consists of 4 line display arduino and resistance measurement circuit. When the underground cable is used to distribution in the urban area sometime fault occurs is an underground cable that time finding fault. We make use of this voltage across change resistors to detect the fault. I am working on a project called arduino based underground cable fault detection system.

Lcd display which dis plays the faults in kilometre. 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. 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. Detection of fault location in underground cable using arduino 2.

The underground cable system is a common practice followed in many urban areas. 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. Whatever the fault is the voltage of the cable has the tendency to change abruptly whenever a fault occurs. 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. Main component of the underground cable fault detection circuit is low value resistance measurement.
