Electrical Cable Testing by Pulse-Arrested Spark Discharge (PASD)
Technology Summary
Sandia has developed an advanced electrical wiring diagnostic system capable of detecting insulation defects in complex wiring systems. The portable diagnostic system detects and accurately locates hard to find insulation defects as breached insulation, chaffing, and insulation cracks. PASD could greatly reduce the time required to track down wiring defects, as it can typically locate these defects within inches.Description
The PASD technique uses a high-voltage, low-energy, short pulse to induce an electrical spark breakdown at the site of an insulation defect. The pulse energy is insufficient to damage insulation or the conductors within wiring systems. PASD has been demonstrated to be effective in several challenging environments and has consistently detected wiring system defects, which cannot be seen through visual inspection.Benefits
