This video shows the electrical tree growth until the breakdown, using an optical camera. The electrical brakdown tube was then reconstructed through X-ray computed tomography (see video “Electrical tree breakdown 3-D X-ray tomography”)
Work conducted at The University of Manchester, United Kingdom.

Imaging technique : optical camera
Dielectric material : epoxy resin
Electrical stress : 10 kV @ 50 Hz /point-to-plane electrode geometry
