high-voltageswitchgear joints for testing

The high voltage in switchgear creates stress for the materials being used in the equipment. Therefore, insulation tests are recommended. In principle, GIS systems require exactly the same tests as other systems. However, they are often difficult to access and this is why they require special solutions.
