Energy Meter Reading
Power consumed is shown by the energy meter in form of 1 unit or 1 kilo watt hour of energy consumed. 1 kWh refers to the electrical energy required to provide 1000 watts of power for 1 hour.
The units of energy consumed are detected by the energy meter which shows the amount of power consumed in form of the energy units. Energy meters are of two types Electromechanical Meters and Electronic meters. For both the meters, reading is done from left to right.
Electromechanical meter consists of an aluminum disc positioned between two electromagnets, one of whose coil is connected to the load and is the current coil and the coil of another electromagnet is connected to the supply voltage. The interaction of the fluxes between the two coils is responsible for providing a torque to the disc, which starts rotating, with the revolutions proportional to the load current. The counter records the number of revolutions and displays them, which indicates the energy consumed.
Prepaid Energy Meter (AT89S52)
A scheme of Electricity billing system called PREPAID ENERGY METER WITH TARIFF INDICATOR 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.
Every consumer can buy a memory card (is nothing but an EEPROM IC) with a password stored inside it using a MC program. The memory card is available at various ranges (ie. Rs 50, Rs 100, Rs 200 etc).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 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. In our project we also have a provision to give an alarm sound to consumer before the whole amount is reduced.
You can also find the Card programmer circuit and program from the download. So that you can easily create your own cards.
Here's the procedure to create the cards.
How to program a new card.
For making a unit price card for Rs 2.50
1. Insert the card into the Programmer
2. Dial 1*0250#
The format is
1 for unit price
* for start process
- Higher digit of the unit price
- lower digot of the unit price
- Higher digit of the unit paise
- lower digot of the unit paise
3. The red led will blink for every key press
4. If the programming done sucessfully then the Green led will long Blink finally.
5. If it fails then the RED led will give a long blink
For making a Recharge card for Rs 400
1. Insert the card into the Programmer
2. Dial 2*0400#
3. The red led will blink for every key press
4. If the programming done sucessfully then the Green led will long Blink finally.
5. If it fails then the RED led will give a long blink

Abstract:
A scheme of Electricity billing system called "PREPAID ENERGY METER WITH TARIFF INDICATOR" 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.
Every consumer can buy a memory card (is nothing but an EEPROM IC) with a password stored inside it using a MC program. The memory card is available at various ranges (ie. Rs 50, Rs 100, Rs 200 etc).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 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. In our project we also have a provision to give an alarm sound to consumer before the whole amount is reduced.

Prepaid electricity meter reduces the billing systems and growth to new technology as a mobile systems & online payment modes for electricty Billings. here data transmission is based on gsm technology.and this system record the Data according to the Tarrifs and deduct the payment as its units produced. In any case of no payment its relay operate and cut the suplly from meter untill it recharge again.
