The electricity theft has appeared as a major problem in power divisions in particular in the expanding countries. In some nations this is so strict that governments are acquiring losses instead of income.In some cases government has to supply subsidies to the power division to keep a reasonable price of power.The term GSM stands for global system for mobile communications is a digital wireless n/w standard designed by standardization teams from major European telecommunications workers and designers.
They give an extra functionality with a real-time or near real-time reads, monitoring the power quality and power outage notification.
They permit price setting agencies to initiate different prices for utilization based on the season and time of day.
It is a single chip computer and is a low cost programmable device. To know more about this, please refer the link: 8051 Microcontroller Architecture and Its Applications A smart card is a one type of integrated circuit card (ICC) and it is a pocket-sized small card with fixed integrated circuits.
The smart card is made with a plastic card with a credit card size with an embedded chip that can be loaded with information.
This is a unipolar relay driver IC with max 50V o/p voltage and 500m A output current.
It comprises of an eight Darlington pair transistors, which have a peak rating of 600m A and can hold up 50V in off-state. Smart energy meters go a step advance than simple automatic meter reading.Electricity bill can be paid using prepaid electricity billing system. Smart card is similar to that of SIM card which should be recharged same as that of mobile recharge card.Based on the usage of power we need to recharge the card by placing it in the card reader.The applications of smart card include in telephone calling, electronic cash payments, etc.To know more about this, please refer the link: What is Smart Card Authentication and Its Applications S1mart Card The relay board includes three SPDT relays & a ULN 2803relay driver.Different technical and non technical techniques were projected in the past to notice electricity stealing.Some of the technical methods to identify pilferage are utilize of central observer meter on harmonic generator, secondary terminals of distribution transformer, extreme learning machine, genetic support vector machines & a power line impedance technique.Robbery electricity, avoiding a meter, billing wrongdoings and not paid bills.Billing irregularity comprises wrong meter reading taken by bribed service man.The prepaid amount is stored within the memory of the Smartcard.Whenever the amount in the smart card becomes zero on power consumption, the Microcontroller turn offs all the loads by generating a buzzer sound.
