| Abstract: | The paper synthetically analyzes three factors to determine filthy classification and mainly studies the problem of using the equivalent salt deposit density as quantitative parameter. The basic measure to prevent pollution flashover is to decide the creepage distance with saturable salt deposit density. Finally, the paper inquires into the advantages of adopting patial face electrical conductivity as quantitative parameter for determining filthy degree. |
