 To increase the distribution rate of present electric supply which is 70% to 100%.  Improving the supply to house holds without interruption.

 Using power lines without using extra cables.  Using Automatic meter reading.

 A technique to facilitate remote readings energy consumption.  Automatic Meter Reading system via Power line Communication is set in a power delivery system, a detection system for illegal electricity usage is possible. Bring “intelligence” into the revenue cycle and manage it: The revenue cycle includes metering, billing operating, customer and the services.

 Smart automated process instead of manual work.  Customized rates and billing dates.  Detection of tampering of Meters.  Accurate measurement of transmission losses.  Better network performance and cost efficiency.  Demand and distribution management.  Better company credibility.

 Rewiring circuits to avoid an electric meter.  Tapping into another customers electrical lines.  Fraudster might use meters that are billed at lower rates.  Fraudster risks electrocution and detection.

 Power meters with PLC modules will be installed near the top of the power poles.  Meters installed in high places will send data of the used amount to each household through power lines.  Homeowners can then check the amount used on the displays installed in each house.  This means that the measurement function and the display function of the meters will be separated.

 Each power meter is connected to an optical fiber network, and information of the amount used by each household is sent to the power companies.  If the power companies find that a payment is delinquent, they can remotely stop the power supply by controlling the meters through the optical fiber network.

 Using the mechanical objects.  Using a fixed magnet.  Using the external phase before meter terminals.  Switching the energy cables at the meter connector box.

 Using the mechanical objects: To prevent the revolution of a meter, so that disk speed is reduced and the recorded energy is also reduced.  Using a fixed magnet: To change the electromagnetic field of the current coils. Hence, the recorded energy proportional to electromagnetic field.

Using the external phase before meter terminals: This method gives subscribers free energy without any record. Switching the energy cables at the meter connector box: In this way,the current does not pass through the current coil of the meter, so the meter does not record the energy consumption.

 PLC is a kind of communication technology, which uses Medium Voltage and Low Voltage distribution network as the communication media to implement transmission of data, voice and real time image. Components: 1. Power Line Carrier Unit which provides signal transmission and reception. 2. There is a Coupler used for “clamping” around a live wire thus injecting the communication signals into the power line. 3. PLC modem

 The recorded data in KWH meters for subscriber are sent to host via PLC modems which are placed in their locations.  Energy meter chips are located in connection point and read the energy in KWH and also send the data to host unit.  The two recorded energy data AMR& PLC are compared in the host PLC; if there is any difference between two readings an error signal is generated. This means that there is an illegal electricity usage in the network.  Then, the subscriber address and error signal are combined and sent to the central control unit. If it is, requested, a contacter may be included to the system at location to turn off the energy automatically.

 optical fiber networks enable power companies to prevent power theft.  To grasp the actual amount of power consumed by district or by each household in real time.  To control the amount of power supply.  The waste of power can also be reduced.  Wide spread use of the power meters with HD- PLC modules is expected to reduce regional disparities in information, or the ‘digital divide’.

 IT DOES NOT AFFECT TE POWER SUPPLY.

 This study show that if the AMR and detector system are used together, illegal usage of electricity may detected.  The system functions with real-time monitoring users and burden forecast, which uses MV&LV PLC as its transmission media. The system is integrated with power management and burden control. Once this proposed system is tried in real power lines, the distribution losses can be reduced effectively.
