The expression of dielectric losses in cables

DIELECTRIC losses in cables depend upon the characteristics of the current, the dimensions of the cable and the specific qualities of the insulation. In order to compare the specific qualities of different insulations with respect to dielectric losses, it is desirable to find a method of expressing these specific qualities independently of current characteristics and cable dimensions. This will permit different insulations to be compared even when tests are made at different voltages, or on cables of different sizes. A method of attaining this result is here suggested.
