Online Condition Monitoring of High-Voltage Overhead Power LinesBy: Prashanth G R USN : 2BV09EE039

Need for Online Condition Monitoring Sag of High-Voltage OH power lines may limit the

operability of power lines. Heavy loads due to icing or vibrations excited by the wind streams increase the risk of line breakage.

Communication to a Control Station System Requirements: It should collect data autonomously. It should provide the comprehensive view of

supervised line. Approaches for establishing communication link between monitoring system and control station: 1. Use of conductor for wire bound communication . (Outdated) 2. Wireless Communication system. (Present System)Dept. of Elecrtical & Electronics Engg., BVBCET
