GSM Based Transformer Health Care Monitoring with Overload Alert and Protection

The power transformer is most important electrical equipment. It is used in power Transmission system; they perform the function of transforming the voltage levels. So maintenance of power transformer is required; they are located at different types of geographical areas periodical checking is not possible all the time due to insufficient amount of man power. So that due to this types of reason transformer failure may occur power shutdown. So to overbear this shutdown due to transformer failure we proposed a system for observing the transformer .The objectives of our project is to monitor as well as protect oil level, oil quality then temperature and voltage level of transformer without involving men’s power. If any abnormal condition occurs the message will be send to the control panel .This monitoring system consist of PIC 18F4520 micro controller as well as LM35 temperature sensor, level sensor, GSM and LCD. So that result obtained in the proposed system with suitable changes can be applied to the real time system.
