An Application of IOT and WSN to Monitor the Temperature of AC Transmission Line

Abstract

With the increase in demand for power with population, power quality issue is one of the challenging areas which needs utmost attention. It is a known fact that the transmission of power takes place through transmission lines which are bare conductors and are prone to many natural situations, which degrade the quality of power and also leads to sagging of conductors. Variation in temperature is a commonly affecting parameter over these transmission lines and leads to deviation in the power flow affecting ampacity of the conductors and over a period of time leads to unwanted sag. Monitoring the temperature of transmission lines is done continuosly using LM35 temperature sensor and an application of Internet Of Things (IOT) through thingspeak application platform to track the variations. An Wireless Sensor Network (WSN) environment is created to transmit the temperature data from one node to another using NS-2 platform.
