the electrical power supplies. Electrical stress on the insulation system increases as the voltage increases, and_x000D_
results in partial discharges (PD). At higher voltages, the partial discharges will be disruptive and lead to_x000D_
insulation failure. The integrity of the electrical insulation system of more-electric aircraft is a serious concern_x000D_
under operating conditions of higher electric stress and low air pressure. An aircraft experiences a wide range_x000D_
of operating pressures during ascent and descent. The pressure at high altitudes of 33,000 to 46,000 feet (10 to_x000D_
14 km) drops to as low as 30% of the pressure at ground level. It is known that the dielectric strength of air_x000D_
decreases with altitude, and this increases the risk of partial discharges. The performance of the electric power_x000D_
system components of an aircraft must be reliable at high altitude under sub-atmospheric pressures. Because of_x000D_
this, PD activity measurement under sub-atmospheric pressures has been a topic of interest for the evaluation_x000D_
of aircraft insulation system._x000D_
The industrial partner of this research project, IRIS Power, is a Canadian company that is internationally_x000D_
recognized for their specialization in condition monitoring of rotating machines. The focus of their activities_x000D_
has been mostly on rotating machines that are part of an electric power system installed at the ground level. The_x000D_
proposed research will enable the study and investigation required to expand the PD detection and analysis_x000D_
methods developed by IRIS to the case of motors employed in 'more-electric' aircraft. The main objective of the_x000D_
proposed research is to initiate a collaboration between University of Manitoba's McMath High Voltage Lab_x000D_
and IRIS Power that will enable IRIS Power to expand the applicability of their techniques to PD detection and_x000D_
analysis at high altitudes and low air pressure for monitoring modern 'more-electric' aircraft and extend the_x000D_
