Arc faults are the main reason for numerous fires around the world every year, leading to a few thousand fatalities and billions of dollars of property damage in various air, land and sea commercial and/or residential electric power systems. Arc faults have been blamed for numerous significant aviation incidents including two catastrophic events with total loss of life for flights TWA-800 and Swissair-111. It has been reported that: “The occurrence of smoke, fire or fumes aboard a commercial aircraft presents a potentially dangerous situation. Accident data show in-flight fire with the fourth highest number of on board fatalities and the seventh highest category of accidents. In addition, data from recent years indicate the probability of passengers experiencing an in-flight smoke event is greater than one in 10,000. In the United States alone, one aircraft a day is diverted due to smoke”.

The reliable detection and protection of arc faults poses a significant challenge for airlines, aircraft manufacturers, the military and regulatory agencies such as the FAA. Most of the AFDP research and technology development efforts to date have concentrated on the detection of parallel arc faults because of the ease of differentiating them from other operating conditions due to their high energy levels and potential for serious damage. In contrast, series arc fault currents are limited by the electrical load and are thus more difficult to detect. This tutorial will present critical challenges of implementing a reliable real-time arc fault detection and protection method applicable to aerospace and general industry and review selected simulation/test results.

Dr. Kojori has 25 years experience in the fields of motor drives, power conversion, power distribution, and advanced controls. This includes 10 years of experience in aerospace with Honeywell. Currently, he is a Sr. Principal Engineer in the Advanced Technology responsible for research, development and technology demonstration of advanced Electric Power System technologies. In this role, he is the design authority for integrated High power conversion systems and particularly for the more electric aircraft. Prior to Honeywell, he worked for Inverpower Controls in Burlington, Ontario as a Senior Development Engineer. He led the engineering team that studied, designed, prototyped, installed, and field tested the world’s first arc furnace flicker controller. This system has been successfully in continuous operation for a 120 MVA Electric Arc Furnace at the Co- Steel LASCO Steel-making Facility in Ontario, Canada, since 1997. Prior to that, he was a Senior Research Associate at the University of Toronto’s Department of Electrical and Computer Engineering conducting original research on power devices and systems.

He is a registered professional engineer in the province of Ontario, Canada, a Senior Member of IEEE Industry Applications Society, a member of the Technical Review Committee for the IEEE Transactions on Industrial Power Converters and Power Electronics Society, a member of SAE Power System Organizing Committee and a member of IEEE - Aerospace & Electronic Systems Society. He is an Adjunct professor at the Power Devices and Systems group in the Department of Electrical and Computer Engineering at the University of Toronto and Ryerson University, and is actively engaged in collaborative research in the general area of power electronics, motor drives and teaching and supervising graduate students.

Dr. Kojori’s original work on numerous technology firsts including Integrated AC and DC Current Sensors, Arc Fault Detection and Protection, Hot-Swap of Line Replaceable Modules, Prognostics Health Monitoring, Active Rectifiers and Arc Furnace Flicker Controllers has resulted in 15 patent disclosures, 13 of which are related to the MEA (four patents awarded and 11 pending), seven journal papers, 21 conference papers and numerous other industry presentations, technical reports and proposals. Hassan as received numerous national and international technical achievement awards throughout his career.
