INTRODUCTION OF RSEBINTRODUCTION OF RSEB

• Rajasthan state electricity board started working from july1957.

• This is the body of big organization act , like public limited companies.

• The aim of RSEB is to supply electricity to entire Rajasthan state in the most economical way

PLCCPLCC

• Power line carrier communication has been found to be the most economical and reliable method of communication for medium or long distance.

• Power line carrier communication is the method of transmitting information using power network.

BASIC PRINCIPLE OF PLCCBASIC PRINCIPLE OF PLCC

• The telephone communication system cannot be directly connected to the high voltage lines suitably designed coupling devices.

• These usually consist of high voltage capacitor with polaritical devices used in conjunction with suitable line matching unit (LMU) for matching the impedance of line to that of the coaxial cable connecting the unit to the PLC transmit-receive equipment.

TYPES OF COUPLINGTYPES OF COUPLING

a) Phase to ground coupling

b) Phase to phase couplingb) Phase to phase coupling

c)c) Interline or inter circuit couplingInterline or inter circuit coupling

BATTERY CHARGERBATTERY CHARGER

• PLCC work on rectified AC or main supply, when supply goes off, we make use of a device for proper functioning of PLCC called battery charger.

• This is the device that provide supply to the PLCC equipment for uninterrupted working.

• It provide DC to the panel by battery.

ADVANTAGE OF PLCCADVANTAGE OF PLCC

• No separate wires are needed for communication purpose.

• Both communication and power transfer can be possible on same circuit.

• Power lines provides the shortest route between the power station.

• Higher mechanical strength.• Increased reliability.• Lower attenuation over long distance.• Implementation cost is reduced.

DISADVANTAGE OF PLCCDISADVANTAGE OF PLCC

• Reflection are produced on spur lines connected to high voltage line. This increased attenuation and create other problem.

• High voltage lines have transformer connections, which attenuate carrier currents.

• Noise introduced by power lines is far more than in case of telephone lines.

APPLICATIONS OF PLCCAPPLICATIONS OF PLCC

• Point to point communication.

• Load shading.

• Power line protection.

• Fault indicator.
