Spark testing method is a method of electrical non-destructive testing based on recording electrical breakdowns and (or) changes in the parameters of the test item in the environment or at the section.
Spark testing method is based on the breakdown of air gaps between the surface of a dry insulating coating with a probe or brush electrode connected to one pole of a high voltage source and the protected item (for example, an underground tank) connected to the other pole of a high voltage source directly or through the soil using a groundwire.
Spark testing method is used for testing the quality of electrically non-conductive protective coatings (paint, enamel and other insulating coatings) on pipes and various metal parts.
