∗ This project describes about the detection of

line fault on the transmission lines with exactlocation & will automatically shuts down thedistribution section.

∗ Also ensure the protection of lineman

working in the transmission line.

∗ The mobile detectors sometimes mistakenly

indicate a weak lightning ,ash nearby as astrong one further away- or ice ersa.

∗ There is no special protection system for lineman.

A 7SM m4dem is a speciali>ed type of modemwhich accepts a S($ card- and operates oer asubscription to a mobile operator- just like a mobile

phone.rom the mobile operator perspectie- a *S$ modem

looks just like a mobile phone.

;hen a *S$ modem is connected to a computer- thisallows the computer to use the *S$ modem to

communicate oer the mobile network.;hile these *S$ modems are most fre%uently used

to proide mobile internet connectiity- many of themcan also be used for sending and receiing S$S and$$S messages.

A -e0ay is an electrically operated switch. $any relaysuse an electromagnet to mechanically operate a switch-but other operating principles are also used- suchas solid6state relays.

Relays are used where it is necessary to control acircuit by a low6power signal Iwith complete electricalisolation between control and controlled circuitsJ- orwhere seeral circuits must be controlled by one signal.

Relays with calibrated operating characteristics andsometimes multiple operating coils are used to protectelectrical circuits from oerload or faults

∗ The project is designed to send in an alertmessage as soon as there is a fault. (n this modelwe predict the place of fault using a distancefrom pole to pole. (n future we can hae a *1Sattached to it that would exactly send thelocation in terms of longitude and latitude.
