INTRODUCTION

• A scheme of Electricity billing system called “PREPAID ENERGY METER WITH tamper proof system” can facilitate in improved cash flow management in energy utilities and can reduces problem associated with billing consumer living in isolated area and reduces deployment of manpower for taking meter readings

COMPONENTS USED:

• Pv89 series• rs232• MCT2E• CRYSTAL OSCILLATOR• CAPACITORS• RESISTORS• POWER SUPPLY• LOAD• relays

WORKING

• In our project we have given the name for memory card as smart card. When the consumer insert a smart card into the card reader which is connected in “prepaid energy meter with tariff indicator”kit.Then the card reader will read the stored information and delete the information from the EEPROM IC(smart card) using the MC program. So that the smart card cannot be reused by others. Suppose if a consumer buy a card for Rs.50/- he / she can insert this amount through the card reader so that prepaid energy meter with tariff indicator kit will be activated. According to the power consumption the amount will be reduced. When the amount is over, the relay will automatically shutdown the whole system.
