Abstract :
The subject ¿Results of Research on Insulating Oils¿ having been placed on the agenda for the meeting in June 1925 of the Paris Conference on Large High-Tension Electric Supply Systems, this paper was prepared as a contribution from the British delegation. The early experiences with oil as an insulating and cooling medium are first briefly reviewed, showing the recognition of the several essential characteristics. The paper then shows the fundamental attack which has been made upon the sludge problem in Great Britain, and outlines the organized research inaugurated by the Institution and continued by the Electrical Research Association. The results obtained are briefly reviewed. A Bibliography is attached, and certain Reports of the Electrical Research Association which have been published in the I.E.E. Journal were included as Appendices to the paper when presented to the Paris Conference.
