Considerations for Electrical Bonding

May 15, 2014 Michael Traskos

Electrical bonding is the practice of connecting equipment cases or structure to ground to prevent electric shock. This provides a return path for any stray voltage that the case may be exposed to via component failure (e.g. wire shorted against case). The reason why proper electrical bonding techniques are so important is that it protects […] Read more

270VDC arcing in aircraft wiring

April 15, 2014 Michael Traskos

In a recent presentation to the SAE at the biannual meeting, Lectromec presented a summary of the work that was performed by several companies and the Federal Aviation Administration (FAA) last summer. These tests were performed at the FAA’s Technical Center in Atlantic City on 270VDC in aircraft wiring. There were four test objectives: Perform […] Read more

7 considerations for aircraft wire separation

March 30, 2014 Michael Traskos

The development of a safe, reliable, and easy to maintain Electrical Wire Interconnection System (EWIS) is a challenging task. The considerations range from selecting each EWIS component, to matching the load and Electromagnetic Interference (EMI) requirements of the connected devices, to ensuring your design can maintain performance across multiple zone environments. EWIS design takes a […] Read more

EWIS regulatory compliance with 25.1707, Part II

January 28, 2014 Michael Traskos

This is the second article in a series on EWIS Regulatory Compliance. The series is looking at the individual components of the Federal Aviation Administration (FAA) EWIS regulations 25.1707. The first article covered section ‘a’ of the regulations. Continuing the examination of the FAA EWIS separation requirements detailed in 25.1707, this article examines the next […] Read more

Aircraft wire failure and incident investigation, Part II

November 23, 2011 Michael Traskos

A couple of weeks back, we wrote the Wire Failure and Incident Investigation article that reviewed some of the characteristics of wire failure and the means to detect them in a post aviation incident investigation. That article focused mostly on the conductor failure mechanisms. The three failure mechanisms that will be covered in this article […] Read more

Arc damage modeling tool and damage at a distance

July 4, 2008 Lectromec Team

The amount of damage that can be caused by electrical arcing events continues to be an important question for both new and legacy aircraft. Many factors can affect the damage done by arcing events. For example, events occurring a short distance from a power bus can have much higher currents and power than those a long distance […] Read more

Understanding series and parallel arcing for aircraft engineers

September 1, 2006 Lectromec Team

Aircraft engineers should know that in recent years have shown increased talk of arcing and the possible damage to aircraft. There have been many examples of these events on aircraft. Recently compiled data from the FAA indicates that between the years 1999 and 2004, there was an average of more than 20 reported electrical arcing […] Read more
