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. ...
An internal low voltage spark gap has been developed as a means of protection for distribution transformers against secondary side surges. The Electric Utility Industry has been concerned about transformer failures attributed to secondary surges, although the failure rate is estimated to be less than 0.5% per year. The entire subject is very complex, but the phenomenon is very much related to ...
