The progress and development of national economy as well as power system, reliability and safety issues of power system have been more important. Development of Transformer Health Monitoring System (THMS) has been done in that reason. Transformer is the most vital asset in any electrical distribution network and therefore it needs special care and attention. The implementation on-line monitoring system integrates Global Service Mobile (GSM) Modem, with single chip microcontroller and sensors. It is installed at the transformer site. The output values of sensors are processed and recorded in the system memory. System programmed with some predefined instructions to check abnormal conditions. If there is any abnormality on the system, the GSM module will send SMS (Short Message Service) messages to designated mobile telephones containing information about the abnormality according to the aforesaid predefined instructions and also other management services such as Voice announcement facility to the concerned department, finding location of Overloading (power theft) of transformers, Plotting GPS points in Google maps, auto police complaint to nearest police station, Overloading (POWER THEFT) sharing to police and finally capturing photos remotely for proof of theft. Our project consists of SMS enabled application and voice-based applications. This project will also consist of the following features by measuring temperature in the transformer such as high or low and measuring oil level in the transformer. Measuring of temperature and oil level in the transformer and taking necessary actions will lead to improve power transmission and it also boost transformer efficiency. This system will be an advanced step to the automation by diminishing human dependency. Thus Transformer health monitoring system offers a more improved transformer monitoring.
