Live-line insulator washing: experimental investigation to assess safety and efficiency requirements

Abstract

A laboratory investigation was carried out to study live-line washing of insulators, with special attention to the two washing procedures which adopt: hand-held jet nozzles; and helicopter mounted nozzles. The aspects related to safety and those related to efficiency and reliability were considered. On the basis of the results, safe working distances and indications to define optimal washing procedures were derived.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
