Elimination of particle effects in SF/sub 6/ insulated transmission systems. First quarterly report

PDF Version Also Available for Download.

Description

The purpose of this program is to develop methods and equipment to eliminate the adverse effect of particle contamination in SF/sub 6/-insulated transmission (CGIT) systems, so that the excellent dielectric properties of SF/sub 6/ can be fully exploited. Presently, CGIT systems are operated at about 10% of the dielectric strength capability of the SF/sub 6/ gas. The program includes theoretical and experimental evaluation of concepts, optimization and verification studies in CGIT systems, and reliability analysis, documentation of designs and economic analysis. Progress is now being made on evaluating alternative conductor and sheath designs to minimize the effect of particles. Materials ... continued below

Presently, CGIT systems are operated at about 10% of the dielectric strength capability of the SF/sub 6/ gas. The program includes theoretical and experimental evaluation of concepts, optimization and verification studies in CGIT systems, and reliability analysis, documentation of designs and economic analysis. Progress is now being made on evaluating alternative conductor and sheath designs to minimize the effect of particles. Materials for solid insulation is being investigated for the same purpose; the effort is presently concentrated on obtaining reliable quantitative measurement techniques of electrostatic properties. Computer calculation of particle trap configurations are being made to determine the optimum trap configurations. A novel particle trapping technique is being using adhesive materials. Manufacture and field control technique studies has commenced with a study of mechanical vibration techniques. An experimental test chamber consisting of a 9 m (30 foot) long 145 kV bus has been designed. This system will be used in testing of particle control concepts and in migration and optimization studies.
