TITLE

Risk Management of Overhead Electric Power Lines

ABSTRACT

A Right-of-Way (ROW) is a land corridor over which power line conductors are stationed irrespective of AC and DC Transmission systems. The High voltage direct current transmission (HVDC) line has less width for the right-of- way compare with HVAC (High Voltage Alternating current) transmission line. Vegetation within the right of way poses the most series risk to power line structures. It is important to review vegetation encroachments within the transmission lines corridor to avoid incidents of power interruptions. Trees overgrown and vegetation unchecked in the ROW width may interfere with electric power lines and leads to dead short circuit and eventually tripping of circuit breakers. Frequent interruptions in power supply can result in economic losses to a utility company. Modern tools such as remotely sensed data and Geographic Information systems can be used for vegetation monitoring around Power line structures in a very efficient way. The Normalized difference vegetation Index (NDVI) is a measured indicator that captures the near infrared and visible bands of Electromagnetic spectrum (EM) to assess the vegetation at the desired target. This paper discusses the technical details of vegetation management for Electric power lines monitoring using NDVI indicator map and GPS Co-ordinates showing the exact location of electric towers on ground
