INTRODUCTION

With the help of this technology lot of Manpower can be reduced and power pilferage can be controlled.

An energy meter is a device that measures the amount of electrical energy consumed by a residence, business, or an electrically powered device.

Electric meters are typically calibrated in billing units, the most common one being the kilowatt hour.

Every consumer can buy a memory card (is nothing but an EEPROM IC) with a password stored inside it using a MC program

SMART CARD

Smart card is adopted as customer card And ESAM security module in meter is Provided to carry out 3DES encryption Authorization. One meter corresponds to One card to achieve perfect security.

DATA TRANSFER

data

Smart card has function of data read back . It is convenientfor management department to monitor the customer’s

Consumption status.

data

METER INDICATION The meter has a tri-color LED to indicate the available

credit levels clearly and directly.

Three levels alarm threshold

Available credit is enough

Available credit ≤ 30%, not enough

Available credit ≤ 20%

Available credit ≤ 10%, meter maybe cut off soon

RECENT INITIATIVES The Sabah Electricity Sdn Bhd (SESB), Malaysia, has awarded a

contract to a local manufacturer to supply 1,080 prepaid meters

Countries such as Thailand, Singapore, and Iran have been showing increased interest in adopting prepaid system

In India, the State of West Bengal has decided to introduce the smart card operated prepaid energy meters in remote islands of Sunderbans. In Mumbai, pre-paid power is provided by the Brihanmumbai Electricity Supply and Transport (BEST)

Undertaking.Tata Power plans to introduce pre-paid electricity in Delhi. Tata Steel is likely to install prepaid electricity meters at its employee township in Jamshedpur.

BENEFITS

Improved operational efficiencies

Reduced financial risks

Better customer service

MARKET DRIVERS

Power sector reforms

Increasing non-technical losses

Opportunities in the emerging electrifying markets

DISADVANTAGE The main disadvantage of the system is, because of huge

electronic hardware involved in the system, the overall system consumes more electric energy

Since it is a prototype module, because of huge hardware the system occupies more space.

The consumer or the electrical department has to spend more amounts for installing this kind of smart energy meters. Economically it is not advised.

CONCLUSION

To save money, the consumed energy corresponding price is displayed for the consumer benefits.

It is hoped that this work helps the electrical engineers for better energy management and its utility in the distribution system for economic liability of the electrical companies.
