Abstract :
The authors report results obtained using a novel technique developed by Olley et al., which is equally applicable to the low resolution (~1 μm) optical examination of water trees; detailed studies of tree microstructure in the scanning electron microscope (SEM) and also to high resolution imaging in the transmission electron microscope (TEM). Specifically, this paper sets out to illustrate the range of water tree structures observed in medium voltage cable insulation, and to describe how these are organised internally
