Arc Damage Modeling Tool

Summary of Arc Damage Modeling Tool Based on over 3,000 arc damage assessment tests, the Arc Damage Modeling Tool (ADMT) is the state-of-the-art for wire failure damage assessment The ADMT is capable of predicting the damage to both direct electrical arcing (direct contact) and indirect arcing (damage from the arc plume) Data generated can be […] Read more

The impact of series arcing

September 15, 2014 Michael Traskos

While electrical arcing on aircraft is often associated with a dramatic failure event, a much more common occurrence on aircraft is series arcing. Series arcing can contribute to overheating and component damage, reduction in signal quality, and poor/sporadic performance of electrical equipment. In this article, we discuss the basics of series arcing, the failure effects, […] Read more

2 EWIS insights from a presentation at the AIAA conference

March 23, 2014 Michael Traskos

Th 51st AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference was held on January 2010 and included presentations of a wide range of technical papers. From the perspective of EWIS, authors McCabe and Cyphers reported on A Study of Over-Current Protection, Electrical Arcing, and Fire Protection. Their research objective was to gather data for ballistic threats […] Read more

Visual inspection of electrical wiring for aircraft: A quick guide, Part II

March 15, 2012 Michael Traskos

This is intended as a quick guide for those performing visual inspection of electrical wiring for aerospace. There is more that needs to be considered than what is covered in this article, but hopefully this can be used as a starting point. Each of the items discussed will be addressed in greater detail during this […] Read more

Guidelines for aircraft wiring: Magnet wire

January 30, 2012 Michael Traskos

Magnet wire is a conductor (copper or aluminum) with a thin insulation used in motors or transformers that is used in aircraft wiring. The wire is wound around a core to generate a magnetic field when an electrical voltage is applied – hence the name magnet wire. A key characteristic of a magnet wire is […] Read more
