The behaviour of transformer oil and other fluids used for the cooling and insulation of power system equipment is significantly influenced by enforced motion. Not only can charges generated by streaming electrification1 accumulate to prejudice dielectric integrity, but the dielectric strength of the fluid is also altered per se2 by the actions of the flow in a complex, but predictable, manner. Both...
Liquid insulation occupies a key position in the range of electrical insulating materials. We can conceive of a volume of empty space to which matter is added, molecule by molecule, until the vacuum is transformed, in stages through low pressure gas, high pressure gas, liquid of low viscosity, liquid of high viscosity, to an amorphous solid. First assumptions might be that as the phase changes then...
