Dielectric Strength - Data Sheet

To test the electrical insulation effect, the breakdown voltage can be measured similar to DIN EN ISO 2376. Flat and almost flat surfaces can be measured. Near edges or sharp-edged angle transitions the measurement is not permitted. The test is - if measured to the point of sparking - destructive. In modified form with "wet" contacting, the finest cracks can be detected in insulating layers. Fields of application are testing of components (e.g. for coils, transformers, magnets, generators) and their Insulation layers for the testing of: Oxide layers on anodised aluminum, magnesium etc. Paint coatings, thickness influence and error checking Electrical insulating films
