Of course, most engineers know the main principles of high-voltage technology and how they apply to design. This article reaches further into this arena, looking at some of the less-discussed, but nonetheless important, areas of HV technology.

Let’s begin with “water treeing.” This little-known mechanism is a degradation mechanism in a subsea cable’s insulation. It involves the formation of dense networks of channels and micro-voids that become filled with water.
