DESIGN AND IMPLEMENTATION OF WEB ENABLED ENERGY METER USING MICROCONTROLLER

The energy meter is the device used to measure and record the power consumption in a consumer area on a KWH basis. In our project, we calculate the power consumption and find out the amount to be paid for the usage. Our module replaces the existent analog meter into digital meter, which is to transfer the power reading to the sub-station.

Here, we measure the power reading with the help of a potential transformer and current transformer. The power here is calculated by the product of the current value and the voltage value from the current transformer and potential transformer respectively. The analog outputs of the transformers are conditioned using suitable signal conditioning circuits like ADC0809.

The output is sent to a microcontroller which reads the current value and the potential value from the respective transformer. It then converts the value to power. The calculated value is transferred to the client system using RS232 serial communications.

Java is used as a bridge to connect the client and web server. The reasons behind choosing java are it is a platform independent language and it is a very secure. The obtained value is transferred to the web. The web server processes the data and finally transfers it to the data receiving station through Ethernet. The EB station checks the obtained value and generates the billing statement through the two way communication. Thus, the consumer and the EB dept, benefit through our project.
