【 Detection Principle and Method 】

The insulation and anti-corrosion layer on the metal surface is too thin, and the resistance value and air gap density at the leakage iron and leakage micropores are very small. When high voltage passes through, air gap breakdown occurs, causing spark discharge and generating a pulse signal to the alarm circuit. The alarm emits an audible and visual alarm,Pipeline electric spark testerAccording to this principle, the purpose of leak detection of the anti-corrosion layer can be achieved.
