A transient technique for the measurement of the thermal conductivity of non-metals is described. A small sample of material is held between a hot copper block and a cold base, and the thermal conductivity of the material is deduced from the exponent

It is shown that the internal strain present in resin insulation by virtue of its manufacture changes under the influence of vibrational electrostatic forces associated with normal operating fields. This is an important observation since the tree-lik

Using an integrated circuit multiplier, the authors have developed a wattmeter capable of measuring watts, VA and VAR in the same instrument. Its power factor range and frequency response together with its cheapness have enabled this instrument to be

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1978.
Kerr type1,2 electro-optical effects have been detected and measured over a range of temperatures in polymethyl-methacrylate (PMMA). The observed birefringence is very much lower than in nitrobenzene, for example. It nonetheless appears possible that
