Design of Single Phase Prepaid Anti-theft Energy Meter

The proposed project involves designing of energy meter which gives the reading without the person visiting each house. There are three components of meter viz. Global System for Mobile communications (GSM), Code Division Multiple Access (CDMA 2000) and Digital Advanced Mobile Phone Service (D-AMPS). GSM modem contains a SIM card for SMS at the consumer side and SMS gateway at the utility side to send and receive the messages. For communication, CDMA provides access code between partners that are called PN codes. Pilferage of electricity can be substantially reduced as its working is just like a mobile wherein the payment has to be made before utilizing the energy. Data transmission would be charged at standard SMS rates. The transmission of readings at low cost would ensure that power consumption values could be transmitted more regularly at far-flung station. It can be combined with other technologies such as satellite communication which is very sensitive to climate change. When combined with CDMA technology data transmission is improved and interference is mitigated. This particular method can be extended to industrial purpose. For industrial purpose we have to calculate the losses in transmission and distribution network.
