How They Find Invisible Cable Flaws with Electric Sparks

Ever wondered how engineers detect microscopic holes in buried cables? This video reveals the fascinating science behind high-voltage spark testing, also known as holiday detection. By sending thousands of volts across the cable surface, inspectors can pinpoint defects invisible to the human eye—protecting critical infrastructure like gas pipelines, power cables, and oil lines from leaks and corrosion. #SparkTesting #CableInspection #HolidayDetection #HighVoltage #Engineering #Infrastructure #QualityControl #NonDestructiveTesting #IndustrialTechnology #HowItsMade
