ABSTRACT: Power transformers are one of the most important electrical equipment that is used in power transmission system as they perform the function of transforming the voltage levels. Hence maintenance of power transformer is mandatory; as they are located at different geographical areas periodical monitoring is not possible all the time due to insufficient man power. Due to this reason transformer failure may occur which leads to unexpected power shutdown. To overcome this shutdown due to transformer failure we proposed a system for real time monitoring the transformer. This work proposed a noval real time monitoring system in distribution transformer with communication through a ZigBee network. It obtains the voltage, current, power, energy and frequency of all loads connected at the distribution transformer. The information collected in the measurements are send to a server through a ZigBee network for safe the information. The new real time system build a wireless network with low energy consumption and a large transmission distance with enough conditions to work in an urban distribution electric network. This system makes possible a low cost infrastructure to do a task of save electric magnitude as well as possible diagnostic of the electrical network. KEYWORDS: power transformer, monitoring, EEPROM, ZIGBEE. I. INTRODUCTION Home automation is a method of controlling home appliances automatically for the convenience of users. It also involves switching on & off electrical appliances like air-conditioners or refrigerators when a desired temperature has been reached. It also is used to secure a house from thieves by sending alerts to the nearest police station. This system principally monitors electrical parameters of household appliances such as voltage and current and subsequently calculates the power consumed. As WSN’s are having many advantages, here we have designed smart meters predicting the usage of power consumption. However it is low-cost, flexible, and robust system to continuously monitor and control based on consumer requirements, ZigBee technology for networking and communication, because it has low-power characteristics, which enable it to be widely used in home and building environments. The demand of electric power for house hold purpose, commercial purpose and industrial purpose increases day by day. The existing method of management of electrical power system is complex as they are generally interconnected with many operating machine units working together. If any of the machine in this interconnected system faces failure entire power system is affected hence careful monitoring and protection of these machines are necessary. Among the interconnected machine transformer which is a static machine which plays key role of stepping up or stepping down voltage levels in power systems based on electromagnetic induction principle. In the existing system monitoring of transformer is done using wired network accompanied with temporary test unit and involving man into action , here continuous monitoring is not possible all the time which may lead to malfunction or failure of power transformer. Our proposed system provides
