Transactions section: Gas-filled-cable research and experience

RESEARCH and engineering studies of gas-filled cable were started about 2 years ago by the company with which the writer is associated and this development work has been carried on coninuously since then. Useful results in the form of practical cable designs have resulted and more will follow in the futures our knowledge of the basic principles off this type of cable increases. The present paper will be in the form of a progress report summarizing results obtained since the first two papers^1,2 on this subject were presented before the IEEE in 1939 and 1942. The same methds of test and analysis of test data described in the previous papers will be allowed and, although an attempt will be made to have the present paper complete in itself, it will be necessary to refer to the older papers frequently to avoid copetition.
