Electrical arcing of aircraft wire is hazardous even over separation

Michael Traskos
Research shows hydraulic line can be punctured without direct contact with arcing wire Recent research conducted by Lectromec confirmed the harmful effects of electrical arcing of aircraft wire events even in the presence of positive separation between the arcing source and the arcing target. Laboratory tests using hydraulic lines as arcing targets showed that, even […] Read more
