The chapter describes the rigorous testing procedures for insulators used in electrical systems. Insulators are first subjected to a pressure test using fuchsine dye, followed by a thermal test involving immersion in boiling and iced water. After multiple cycles, they undergo a flashover test at a high frequency to detect dielectric defects. The insulators are assembled using Portland cement and treated with weather-proofing compounds before undergoing tension tests under 10,000 lb. weight and high-frequency flashover. Dr. J. H. Hutton presented findings from the 1931 Indian census to the Royal Society of Arts. Despite some inaccuracies, the census showed a population increase of 10.6% from 1921 to 1931, exceeding previous records. This increase was most significant in Native States and less fertile regions, possibly due to irrigation expansion. Urbanization rates remained stable, with the urban population accounting for 11.0% in 1931 compared to 10.2% in 1921. The female-to-male ratio is declining, currently at 940 females per 1000 males. The Medical Research Council appointed new members to the Industrial Health Research Board. The Bisset Hawkins Gold Medal was awarded to Dr. T. H. C. Stevenson for his work in statistics. The Harveian Oration will be delivered by Sir George Newman. The North-East Coast Institution of Engineers and Shipbuilders awarded several medals for contributions in engineering and shipbuilding. The Wiltshire Archaeological Society announced the donation of prehistoric sites near Stonehenge and Avebury to the nation. Various job applications are invited for positions in education, research, and engineering.The chapter describes the rigorous testing procedures for insulators used in electrical systems.
