I. Introduction
Over recent decades, there has been tremendous progress in the efforts to move toward more electric aircraft [1]. Many subsystems that previously employed mechanical, hydraulic, and pneumatic power have been fully or partially replaced with electrical systems [2], [3]. Moreover, Civil-aircraft manufacturers have identified that these ‘More-Electric’ technologies can help reduce overall life-cycle cost and weight for the aircraft operator, as well as optimize performance [4]. To achieve a progressive structure, the aircraft industry is developing required mechanical, electrical, and electronic components, and looking at new concepts to protect and monitor them throughout their operating life [5].
