The Application & Business Benefits of Aerial Laser Survey Techniques used in the Management of Clearance Infringements

Key work done by network mapping over the last 4-7 years, has been in relation to the development of best practice in the acquisition of ALS data; in demonstrating the accuracy of the data obtained from ALS surveys; in the quality management of the accuracy process; and in the practical use of the data for power system applications. This paper describes how the data provided by network mapping is analyzed and used within the UK Electricity Transmission Business, operated by national grid primarily at voltages of 400 kV and 275 kV, to respond to objects infringing normal overhead line clearances, as identified from the surveys. If not managed correctly these infringements present a safety risk to the public, other electricity utilities and our staff. Analyzed ALS data provides a swift response once these issues are identified and identifies the source of the problems and the options for resolution
