Abstract :
The most outstanding developments in the field of dielectrics in the year 1948 seem to have been directed toward applications outside of the field of electrical insulation, but will undoubtedly furnish a better understanding of the fundamental behavior of insulators. The progress in lines directly related to electrical insulation seems to have been steady, but not spectacular. There has been a large amount of publication and, from all the research, some instances where new and apparently promising directions have been taken will be mentioned.
