Effect of humidity on the power frequency flashover voltage of insulators and gaps at varying temperature conditions

The work reported in the paper is a part of data collection on the effect of humidity on the flashover voltage of insulators and gaps at different temperature conditions. In the present investigation, studies were made at two constant temperatures of 30°C and 37°C. The corresponding humidity variations were 11 gms/m3 to 25 gms/m3 and 16 gms/m3 to 30 gms/m3 respectively. Insulators and air gaps were subjected to a power frequency voltage, under the above conditions. The results are presented through graphs.
