INTRODUCTION

Here the advanced technology used in prepaid energy

meter is being introduced.

This energy meter produces pulses accordingto the load and this meter is converted as

prepaid energy meter using smart card, hencethis meter can be called smart energy meter.

This kind of smart energy meters also can beinstalled at each and every house, where the

state electricity department going to supply theconventional energy. Now a days energyMeasurement and electric energy pilferagedetection has become prime importance for thestate electricity department.

ABOUT THIS ENERGY METER:-

The overall system can be called as AMRAutomatic Meter reading! system, the main

advantage of AMR system is that theconsumed energy price can be calculatedand at the same time price amount inrupees! can be displayed automatically.

"inally the simplest form of smart metering is a

display meter, which allows consumers tomonitor consumption in money terms ratherthan k#h.

Hence by the use of this energy meter a lot of

manpower can be reduced.

The prepaid energy meters in the market today are

coming up with smart cards to hold information onunits

consumed or e$uivalent money value.
