Abstract
The data given pertain particularly to the field of three-conductor three-phase cables when supplied with three-phase voltage, and are primarily the solution by physical measurements of some of the geometric problems of the three-conductor three-phase cable. Data are given so that it is possible, from electrical measurements on three-conductor cable, to determine certain specific quantities as permittivity, resistivity, etc. of the dielectric of three-conductor cables in the same way as can readily be done for single-conductor cables, from geometric considerations. Also, there is shown the potential and stress distribution in a three-conductor cable. The most extensive data are based on measurements made with electrodes in an electrically conducting liquid, thus simulating a homogeneous dielectric. Also exploring electrodes were built into some actual three-conductor cable, and measurements were made when three-phase voltage was supplied to the conductors.
