GIDED BY:- Mr. Vikas Bhalla Seminar Presentation Prepaid Energy meter GIDED BY:- Mr. Vikas Bhalla SUBMITTED BY:- Mukesh Meghwal 12ECTEE203 Department of Electrical engineering Govt. College of Engineering and Technology, Bikaner.

Agenda Problems in Power Sector Introduction Features Applications Advantages Future Integration.

PROBLEM IN POWER SECTOR Recovering electricity dues from Government departments Apartment blocks, Commercial complex Rural areas etc. Electricity Theft Complicated Billing Process Wastage of Energy.

introduction Prepaid Energy Meters: It is the new concept in world of electricity measurement. This concept is not only beneficial for electricity measurement but also has the capabilities to prevent theft and misuses of electricity. The concept of PEM (Prepaid energy meter) is very similar to prepaid mobile system, you recharge and spend accordingly.

Contd…….. Prepaid Energy Meters: When the purchased units are used up by the consumer the meter disconnects the power supply until the next recharge. The system will automatically notify the consumer to recharge before zero balance; unit recharge will be done by the service provider.

Prepaid Electricity System Design

FEATURES Compact wall mounting design Cost effective ‘Pay as you use’ Three phase electricity metering Accuracy Better operational efficiency as no need manpower for meter reading. Better Energy management.

Structure of Pre-paid smart card Energy meter

APPLICATION Shopping Malls / Multiplexes Residential Townships / Apartments Commercial Buildings Employee Quarters

ADVANTAGES Cost of manpower for billing / collection is substantially reduced. Inform consumers before zero balance by LED indication & LCD reading, so that consumer can plan when to recharge. No billing disputes Allows consumer to budget electricity expenses Upfront payment for electricity and hence low over heads for service providers. Helps consumer to contribute towards energy conservation.

FUTURE INTEGRATION It can be used as three in one meter for Electricity Water Gas.
