Assessment of arc tracking hazards in high voltage aerospace systems


Arc tracking is already a significant issue in existing aerospace electrical systems operating at 115VAC and 230VAC and can cause significant damage to wiring. Moreover the impact of arc tracking on future systems operating at higher voltages, such as series hybrid electric systems, has not been assessed. This project should quantify the risk of arc tracking in megawatt scale aircraft electrical systems operating at high voltages (>1.5kV DC). The project should develop the fundamental understanding and consider what measures should be taken to safeguard the aircraft electrical system from resultant damage. The project should consider the configurations of cable likely to be used in higher voltage applications and the different voltage types (DC, AC, converter fed). Please refer to the full topic descriptions document published in this call.
