“…Depending on electrical network parameters including the power source and the equivalent impedance, such faults may lead to stabilized arcs as long as the protections are not activated and a self-extinguishing process is initiated. Once the arc has been extinguished and the system reenergized, the phenomenon can reemerge, depending on applied voltage, load current, chemical composition and thickness of the partially damaged insulation [45].…”

Next generation aircrafts will use more electrical power to reduce weight, fuel consumption, system complexity and greenhouse gas emissions. However, new failure modes and challenges arise related to the required voltage increase and consequent rise of electrical stress on wiring insulation materials, thus increasing the risk of electrical arc appearance. This work performs a critical and comprehensive review concerning arc tracking effects in wiring insulation systems, underlying mechanisms, role of materials and possible mitigation strategies, with a special focus on aircraft applications. To this end an evaluation of the scientific and technological state of the art is carried out from the analysis of theses, research articles, technical reports, international standards and white papers. This review paper also reports the limitations of existing insulation materials, standard test methods and mitigation approaches, while identifying the research needs to comply with the future demands of the aircraft industry.

“…Arc faults occurring in wiring systems also called 'arc tracking phenomenon', are an issue that has been known for decades in the aeronautic industry [1,2] and space application [3][4][5]. With a significant amount of energy released in a very short time, arc faults can severely damage electrical installations and lead to dramatic accidents.…”

A systematic study of arc faulting between two cables in aeronautic conditions is performed and a power balance of the arc is realized. Electrical characteristics and radiative heat flux are recorded. The effect of the current mode (AC/DC), cable material and pressure is highlighted with the assessment of the power balance, which includes the mean power of the arc, power transferred to the cables that can cause melting and vaporization, and the power lost by radiation, conduction and convection in the arc column. The evaporated mass of the cables can be estimated in this way. Optical emission spectroscopy measurements of the induced plasma are performed rendering the overall temperature of the arc using a Boltzmann plot method. The overall temperature is higher for copper-contaminated plasma than for aluminium-contaminated plasma. Despite the erratic behaviour of the plasma, the trend shows that the DC as well as the use of lighter aluminium-based cables lead to higher power.
