Advanced Vehicle Wire Health for the 21 st Century 2004-01-3159

Traditionally, vehicle power wiring safety has consisted of a reactive thermal circuit breaker that responds to an overload condition. In addition, maintenance operations have been reactive as well, searching for a possible damaged section of wiring in a large and often difficult to access wire bundle. Advancements in detection of changes in impedance, arc, corona, and reflectometry to measure general wire damage have the potential to automate the process, while increasing vehicle safety and reducing costs. Some of these technologies are also pro-active and can warn of a potential problem during routine maintenance checks using hand held instrumentation or if embedded in a vehicle can detect problems prior to power up or after system power up using real-time monitoring.
