Finding Short Circuits in Aging Airplanes

06/20/2006 12:00 PM

Sandia National Laboratories (Albuquerque, NM) has patented a product that can find potentially dangerous short circuits hidden in the miles of wiring behind the panels of aging commerical airliners. The Pulsed Arrested Spark Discharge (PASD) system sends a nanosecond pulse of electricity, fiercely propelled by a high voltage, along airplane wiring bundles. The tiny pulse is powerfully driven so that it can jump gaps in slightly frayed insulation but has so little energy that it is harmless.

This is somewhat similar to what power distribution companies use to find leakage in (especially) underground power cables. I once watched our local power distributor using this method to figure out that a 'beehive' in a distribution box was the culprit!

Will be good if it works. The gear supply authorities use is relatively high energy and usually works. I tried a fault locator some years ago now hand held, battery powered and worse than useless.
