INTRODUCTION
PLCC is the method of transmitting information using power network.
It bridges the gap between electrical and
communication network.
We are able to construct intelligent buildings
containing many devices in Local Area Network
WAVE TRAP
Consists of a number choke coils connected in series.
It prevents carrier currents from entering to the power equipment.
Offer negligible impedance to power frequency & high impedance to carrier frequency
Coupling capacitor
It is a stack of capacitors connected in series.
Has highest possible surge withstand capacity, offer lowest series resistance at carrier frequency.
Used to mount the wave trap on it.
CONCLUSION
Project is based on communication over existing power line
Main advantage:
1. Modern infrastructure simplify the implementation.
2. Both communication & power transfer can be possible on same circuit.
3. Implementation cost is reduced
