Vijaya Kumar Journal On Wireless Communication Networks 2320 - 2351 1 2 24 31 Online Monitoring, Sensors, Wireless Communication, Case Study of Feeders, DAS, Data Acquisition System Indian electricity transmission and distribution system is encountering huge multifold problems in technical and non technical fronts, Thus induction of devices for analyzing, handling and predicting the problems for betterment of energy management. Looking at the scenario the on line monitoring and control system is the only solution to overcome the crises of loss occurred in transmission System, Hence the transmission of energy is monitored by deploying sensors on overhead transmission lines at a very close locations on the support structures on each span. In our work we have used voltage sensors, accelerometers and temperature sensors for collecting data. Thus the collected data will be delivered to the central control centre through GSM communication for immediate action and the data will be stored for further investigations.
