Electrical energy theft ranges between 3 - 30% depending on country. This illegal electricity usage may indirectly affect the economical status of our country . Also the planning of national energy may be difficult in case of unrecorded energy usage.
Revenue protection is a major concern of electricity utilities all over the world , especially energy theft is growing at an ever increasing pace. Now one of the major problems faced by the energy suppliers like KSEB is the illegal usage of electricity.
Electricity theft is a social evil , so it has to be completely eliminated. So our major project named 'Electricity Theft Monitoring System' is focusing on how to detect and monitor the Electricity Theft at a remote KSEB location. The proposed system prevents the illegal usage of electricity. At this point of technological development the problem of illegal usage of electricity can be solved electronically without any human control. Here we use Radio frequency(RF)Technology for wireless communication.


Power consumption and various losses have to be closely monitored so that the generated power is used in most efficient manner.
The aggregate losses of a power system has two components
1) Technical Losses
2) Commercial losses
The technical losses include the losses on transmission and distribution lines, transformers and all other electrical equipments up to the point of supply at consumers premises.


Commercial losses include losses other than technical factors such as theft of power, poor collection efficiency ,revenue non billing, billing error etc.


Electrical energy theft ranges between 3 - 30% depending on country. This illegal electricity usage may indirectly affect the economical status of our country . Also the planning of national energy may be difficult in case of unrecorded energy usage.
In this type of meters the electrical energy consumption is measured based on the induction principle recorded by the resolution of the counter. Ferraris invented this meter in the year 1884.Hence,these meters still called Ferraris meters. The principle adopted by Ferraris was the principle of induction motor. Hence these meters are designed to carry the load current up to 80A in the whole current single and 100A in the three phase meters. For measuring high loads on the LT side, CT operated meters are used. These meters have lo accuracy in the range of 0.2%.The life time of these meters varies from 15 years.


The driving system of this meter consist of two electromagnets. The coil of one of the electromagnet is excited by the load current. This coil is called current coil. The coil of second electromagnet is connected across the supply voltage. This coil is called the pressure coil or voltage coil. An aluminium disc is positioned in between the electromagnets. The supply voltage is applied across the pressure coil. So a current proportional to the supply voltage is flowing through the pressure coil. This current will produce a magnetic flux, major portions of this flux sweeps across the aluminium disc and is responsible for the production of driving torque. And the revolution of the disc is proportional to the load current. The function of the registering or counting mechanism is to record the revolutions continuously a number which is proportional to the revolutions made by the moving system
