This article describes the principles, design and field experience of scratch detectors that detect lubrication failures and scratches without touching the wire. Scratch detectors detect the short circuit through the lubricant layer and its extent, and give an alert based on operator-defined reference values and time limits. Signal can be lost to external processing
