“…However, due to the high voltage levels corona effects are increased [16,17]. Different high-altitude high-voltage tests were conducted in the United States during the 1950s and 1960s [18][19][20] driven by the need to construct transmission lines crossing high-altitude regions. Countries like China [21][22][23][24][25], India, Buthan [26], Nepal [27] and Peru [28], among others, have constructed or are proposing EHV transmission lines and the associated substations, crossing high-altitude regions.…”

Nowadays there are several transmission lines projected to be operating in high-altitude regions. It is well known that the installation altitude has an impact on the dielectric behavior of air-insulated systems. As a result, atmospheric and voltage correction factors must be applied in air-insulated transmission systems operating in high-altitude conditions. This paper performs an exhaustive literature review, including state-of-the-art research papers and International Standards of the available correction factors to limit corona activity and ensure proper performance when planning air-insulated transmission lines intended for high-altitude areas. It has been found that there are substantial differences among the various correction methods, differences that are more evident at higher altitudes. Most high-voltage standards were not conceived to test samples to be installed in high-altitude regions and, therefore, most high-voltage laboratories are not ready to face this issue, since more detailed information is required. It is proposed to conduct more research on this topic so that the atmospheric corrections and altitude correction factors found in the current International Standards can be updated and/or modified so that high-voltage components to be installed in high-altitude regions can be tested with more accuracy, taking into account their insulation structure.

“…The influence of altitude on corona phenomena has been studied in the past, primarily in the laboratory to determine corona onset [3] or at high-altitude test stations to determine its effect on corona loss and radio noise (RI) in the AM broadcast band [4,5]. There has been no extensive study to determine the effect of altitude on audible noise (AN) and television interference (TVI).…”

“…Both corona loss [4] and RI [5] were measured on single and multiple conductors in bundles that were similar to conductors tested near sea level (195 m) Figure 1 as a function of altitude. The relative air density (referenced to sea level) from standard atmospheric tables was used in the Westinghouse formula.…”
