Abstract: Transformers are the main building block in a power system. Any damages in transformers adversely affect the balance of a power system. The damages are mainly occurring due to overloading and inefficient cooling. The main objective of the project is the real time monitoring of the health conditions of the distribution transformer. The parameters such as temperature, voltage and oil level of a transformer are monitored. KSEB facing a big problem in accidents due to faulty lines and line breaks .We are proposing a new low cost system for detecting line breaks and faulty line. The system can isolate the broken line from the feeder and inform the authority .Main advantage of this system is a single device can monitor entire output area of a distribution transformer. Also OTP based lineman protection is enabled. Our device is a microcontroller based intelligent monitoring device with transmitter receiver pair, the transmitter section continuously monitoring line end voltages and reporting the master device using wireless signal, the master device analyze the data from the transmitter and report the authority if any action needed via GSM technology. The master device is using a SMART (Self monitoring analyzing and reporting technology for accident prevention).
