SYSTEM TO CONTROL ELECTRICITY THEFT USING 
SMART PREPAID ENERGY METER 
ABSTRACT 
Power utilities in different countries especially in the developing ones are incurring 
huge losses due to electricity theft. This paper proposes a prepaid energy metering system to 
control electricity theft. In this system a smart energy meter is installed in every consumer 
unit and a server is maintained at the service provider side. 
Both the meter and the server are equipped with GSM module which facilitates 
bidirectional communication between the two ends using the existing GSM infrastructure. 
Consumers can easily recharge their energy meter by sending a PIN number hidden in a 
scratch card to the server using SMS. 
This paper presents some measures to control meter bypassing and tampering. The 
bidirectional GSM communication using SMS ensures the effectiveness of these measures. 
Pilferage of electricity can be substantially reduced by incorporating the proposed measures 
along with the prepaid metering scheme. Legal actions against dishonest consumers can also 
be taken in this system. 
This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage 
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the 
ac output of secondary of 230/18V step down transformer.
