Abstract

In loaded cables, the copper and dielectric losses cause the conductor and insulation to heat up. Normally the dielectric expands 1 to 2 percent more than the conductor in radial direction. A cavity will form between the conductor and the insulation material. The change in the energy stored in this cavity creates an electrostatic force. This force leads to thermomechanical breakdown of cable dielectric. An experimental technique is suggested, designed, and used to measure the electrostatic force.<>
