Step 2 In Underground Cable Fault Location Cable Route Tracing About press copyright contact us creators advertise developers terms privacy policy & safety how works test new features nfl sunday ticket press copyright. This document describes a project to detect the location of faults in underground cables using an arduino board. it discusses underground cables versus overhead cables, common types of underground cable faults, and methods for detecting faults including offline and online methods. it then introduces the circuit used, which works by measuring. Fig. 1. block diagram of underground cable fault detection system. full size image. the appropriate led turns on by itself when the relay for that portion is closed. a voltage drop is conveyed to port a of the mcu as a result of the release of the resistance connected to that specific portion. Basic cable fault locating methods. there are two basic methods of locating an underground cable fault. sectionalizing this procedure, as shown in fig. 1, risks reducing cable reliability, because it depends on physically cutting and splicing the cable. dividing the cable into successively smaller sections will enable you to narrow down the.
How To Find Underground Cable Fault Location By Thumping Method а аґ а а і Fig. 1. block diagram of underground cable fault detection system. full size image. the appropriate led turns on by itself when the relay for that portion is closed. a voltage drop is conveyed to port a of the mcu as a result of the release of the resistance connected to that specific portion. Basic cable fault locating methods. there are two basic methods of locating an underground cable fault. sectionalizing this procedure, as shown in fig. 1, risks reducing cable reliability, because it depends on physically cutting and splicing the cable. dividing the cable into successively smaller sections will enable you to narrow down the. The circuit is consists of 4 line display, arduino and resistance measurement circuit. main component of the underground cable fault detection circuit is low value resistance measurement. it is constructed using a constant current source of 100mamps. it can measure very low value resistance as the cables have around 0.01 ohm meter resistance. Shut downtime down: the need for effective cable fault location is undeniable. megger’s diagnostic systems enable you to not only identify and address cable faults fast, but predict and prevent issues before they impact your operations — all without causing damage to the healthy parts of the cable.
