The demand for uninterrupted quality power is increasing by the day. To maintain quality and continuity of power supply, budding engineers of Potti Sriramulu Chalavadi Mallikharjuna Rao College of Engineering and Technology in the city have come up with an innovative idea to identify the fault through the GSM modem.

Four students — V. Kalu Naik, M.K. Chaitanya, P. Yeswanth Kumar, and S. Karthik Pradeep — who are pursuing Electrical and Electronics Engineering, have designed ‘Line Fault Analyser’ by using a micro controller.

“Analysers will increase reliability in transmission and distribution networks,” the students said.

“Supplying quality power without interruption is a big task for APTransco/SPDCL officials. Engineers, line inspectors, and linemen have to check several points every time to identify the fault, which cause power loss and disturb power supply. Our aim is to simplify the process in detecting the fault and give uninterrupted power supply,” they said.

“Different opto couplers are fixed on the main distribution line (electric poles), which are connected to a sensor reading logic. The output of the sensor reading is attached to the micro controller. Whenever a fault occurs, the micro controller reads every sensor and sends a message to mobile phones, which are pre-specified in the micro controller through GSM network,” said Mr. Chaitanta.

Mr. Kalu Naik said the project was designed in 45 days at a cost of Rs.10,000. One step-down transformer, opto coupler, micro controller (89C52), buzzer, display and GSM modem were used for preparing the kit, he said.

The students thanked college principal K. Nageswara Rao and EEE Head of Department Y. Rajendra Babu for their support in designing the project.

The APTransco officials who examined the project praised the team for preparing the model, said institute’s training and placement officer P. Srinivasa Rao.
