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

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

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
