• RSEB started from 1 July 1957

• It is a big organization and it functionsunder provision electricity act

• !"e aim of RSEB is to supply electricityto entire Ra#ast"an state in mosteconomical $ay

• !"e target of board is to distributeenergy in ne$ areas as possible

!"e communication device used for t"ecommunication over t"e po$er lines is a 234E2.commonly no$n as Po4er Line MO'EM %&28

It $ors as bot" transmitter and receiver. ie. ittransmits and receives data over t"e po$er lines

po$er line modem not only modulates t"e data totransmit it over t"e po$er lines and but alsodemodulates t"e data it receives from t"e po$er lines

By using modulation tec"niues. binary data stream iseyed on to a carrier signal and t"en coupled on to t"e

po$er lines by %&2 t t"e receiver end anot"er %&2detects t"e signal and e:tracts t"e corresponding bitstream
