  4. 4. • 1950 : at a frequency of 10 hz , 10 kw of power , one way: town lighting , remote relay control • 1980 : beginning of researches into the use of electrical power grid to support data transmission • 1997: first tests for bidirectional data signal transmission over the electrical supply network and beginning of research by Ascom(Switzerland) and Norweb(UK) • 2000 : First test carried out in France by EDF R&D and March 8, 2014 Ascom
  5. 5.  In India the largest democracy with an estimated population of about 1.04 billion is on the road to rapid growth in economy because of electricity The theft of electricity is a criminal offence If an automatic Meter Reading system via power line communication is set in a power delivery system a detection system for illegal usage of electricity is possible Power line communication has many new service possibilities on the data transferring via PL with out extra cables March 8, 2014
  6. 6. 1) Using mechanical objects 2) Using the external phase before meter terminals 3) Switching the energy cables at the meter connector box 4) Using a fixed magnet March 8, 2014
  7. 7.  The AMR system starts at the meter. Some means of translating reading from rotating meter dials into digital form is necessary in order to send digital metering data from the customer to a central point. A optical sensor is used to convert the ordinary meter rotation into the digital form. One such technique using optical sensor is shown in the figure .

  16. 16. 1) Every user has two PLC modems 2) An second energy meter must be installed 3) The host PLC unit must be placed in the distribution transformer 4) The host PLC modem and its controller must include two address per every user March 8, 2014
  17. 17. March 8, 2014
  18. 18.  There is no need of extra cables and wires  Accelerating the economic growth  Very suitable for smart grid project  The initial and running cost are low  Distribution loses are reduced March 8, 2014
  19. 19. March 8, 2014
  20. 20.  Breakdown of power line will affect  There needs more modems  Looping from the pole may possible  There should be a host PLC unit near all the distribution transformer March 8, 2014

  22. 22. APPLICATIONS  Leakage current detection  Public lighting ( street lighting )  Power system fault detection  Measurement/Control/Energy-management of electrical power equipments for electrical power companies  Automatic Meter Reading March 8, 2014
  23. 23.  Home security  The remote monitoring /control of electrical house hold appliances  Online games  Home network (LAN)  Remote billing March 8, 2014
  24. 24. CONCLUSION  the proposed detector system to determine the illegal electricity usage via power line communication is very useful and successful.  The system proved that if AMR and detector system are used together illegal usage of electricity might be detected.  Once this proposed detection system are tried in real power lines , the distribution losses in India can be reduced effectively March 8, 2014
