Arcing

Aircraft EWIS failure and the process of electrical arcing

Michael Traskos
The hazard of aircraft EWIS failure and electrical arcing will exist for as long as there is a need to deliver electrical power through wires. While electrical arcing is a common occurrence, the factors that impact an arcing event are often not well understood. This article reviews each step involved in electrical arcing, from what […] Read more

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

Arc flash assessment on naval vessels

Lectromec Team
Arc flash is a problem for many industries; with increased demand for electrical power, arc flash is the likely consequence. To combat this growing hazard, most organizations have taken proactive measures to provide training to their staff in the proper way to protect against an arc flash. This training is the first line of defense in protecting […] Read more

Understanding series and parallel arcing for aircraft engineers

Lectromec Team
Aircraft engineers should know that in recent years have shown increased talk of arcing and the possible damage to aircraft. There have been many examples of these events on aircraft.  Recently compiled data from the FAA indicates that between the years 1999 and 2004, there was an average of more than 20 reported electrical arcing […] Read more
