The system consists of multiple smart wireless transformer sensor node, smart controlling station, smart transmission line sensor node, and smart wireless consumer sensor node. The proposed software module also incorporates different data aggregation algorithms needed for the different pathways of the electricity distribution system. This design incorporates effective solutions for problems faced by India’s electricity distribution system such as power theft, and transmission line fault. The proposed architecture is designed for single phase electricity distribution system, and this design can be implemented for three phase system of electricity distribution with minor modifications.  INTRODUCTION Many developing countries confront widespread theft of electricity from government owned  power utilities. In India electricity theft leads to annual losses estimated at U! .# billion, about $.# percent of %&'. (ho are the losers) *onest consumers, poor people, and those without connections, who bear the burden of high tariffs, system inefficiencies, and inade+uate and unreliable power supply. ine faults may be caused due to over current or earth fault. If there happens to be a connection between two phase lines then over current fault occurs. arth fault occurs due to the earthing of phase line through cross arm or any other way. ow in India, there is not any techni+ue to detect the specific location of the fault immediately. 'ower theft is another ma/or problem faced by Indian electrical system. These two problems can be solved effectively through this architecture. 0y the proposed architecture the above mentioned problems can be solved.  WORKING OF WIRELESS SENSOR NETWORK The sensor networ1 monitors the electrical grid for a specified period of time, which may be daily, monthly or yearly. Thus the (T stores the ma2imum demand for each consumer including the losses. This value is updated only when a new consumer becomes the part of the networ1 345. The measured data from each (6 is send to the neighboring T. The aggregated data is then sent to the ne2t nearby (. Thus the data transfers from (6 tothe corresponding (T through T. The collected data is compared with the measured data by the energy meter plus & l in each T. ormally these two data are almost same. If there is any difference 7dmc8 in the collected data and the measured data, there may be a line fault or a power theft in that segment. arge value of dmc indicates a line fault and small value of dmc indicate a power theft. METHODOLOGY 1 )   Zib!!   (e are using 90ee-':; ;M :< Module. It is engineered to meet I =>?.$#. standards and support the uni+ue needs of low-cost, low-power wireless sensor networ1s. The modules re+uire minimal power and provide reliable delivery of data between devices. The modules operate within the IM ?. %*@ fre+uency band and are pin-for-pin compatible with each other. The 90ee-':; ;M :< Modules interface to a host device through a logic-level asynchronous serial port. Through its serial port, the module can communicate with any logic and voltage compatible UA:T or through a level translator to any serial device. ?8 C#rr!$t Tra$s%&r'!r Circ#itr( : (e are using Allegro A64>B current sensor I6. The A64>B consists of a precision linear *all sensor integrated circuit with a copper conduction  path located near the surface of the silicon die. Applied current flows through the copper conduction path, and the analog output voltage from the *all sensor I6 linearly trac1s the magnetic field generated by the applied current. The accuracy of the A64>B is ma2imi@ed with this patented pac1aging configuration because the *all element is situated in e2tremely close pro2imity to the current to be measured.
