Transformer Load Sharing with S.M.S. Alerting
The main aim of the project is Transformer allocation whenever load is increased for certain value and also sending this change in illumination to the relevant authority via SMS by using GSM Modem. The objective of this project is to preserve the domestic supply and power transformers from overload power. Drop in efficiency and overheating in secondary winding can be obviated with the help of this project. The demand for electricity is increasing every day and frequent power cuts is causing many worriment in various areas like industries, hospitals and houses resulting in load increment hence overload. An alternate arrangement for power is a must. This project uses parallel transformers for load sharing at highest load on first transformer then automatically load transfer on second transformer. Load sharing of the transformer is cinch with the help of this project theme and the life of the transformer is increased. The project is also used as a sustained power supply .If short circuit fault occurs, the transformer will be protected. A microcontroller of 8051 extraction is used. The output of microcontroller is given to the relay drive IC, which switches relevant relay to maintain uninterrupted supply to the load. The output shall be observed the current status, as to which derivation supplies the load is also displayed on an LCD. The global system for mobile communication is used as it is accepted standard for digital communication and is helpful in sending message to authority via SMS whenever load is shared between the parallel transformers.
