Evaluation of advanced technologies for power transformers. Final report. Part I, November 1976-March 1979

Description: The high insulating strength of certain gases, such as sulfur hexafluoride, when used at high pressure, suggests that there may be advantages to compressed gases as the insulating fluid in power transformers. However, simply exchanging the oil for compressed gas in an otherwise conventional transformer design will not yield a significant overall advantage. Compressed gases present the engineer with properties which are quite different from mineral oil. If gases are to be used as the major insul… more

Effects of compressive forces in pipe type cable

Description: Within the thermo-mechanical bending (TMB) phenomenon of underground power transmission systems, compressive cable forces give rise to increasing tape tensions in the cable insulation. Because of their substantial magnitude, these changes in tape tensions play an important role in the formation of soft spots which can eventually cause electrical failure. A theory of the mechanical behavior of power cables under compressive load is presented together with experimental verification of this theory… more

Model of torsional behavior in thermo-mechanical bending

Description: An effort was made to model the response of high voltage transmission cables to the torsional loads which occur in the in situ condition of the cable buried in a pipe. Tests were run on a torsion machine in the laboratory which was able to accommodate a reversal of load. The behavior of the cable was studied as it went through cycles of beng twisted in opposite directions alternately. Strain in the tape was measured, as were torque and angle. Mathematical models were derived to determine the to… more
