Trends in the altering landscape of higher-voltage insulators are revealed via utility interviews. In addition, this behaviour offers fantastic information on what should really be carried out to safeguard these lines against the indirect effects of lightning, whereby consideration should be given to various impulse voltages and also the use of local information and facts of the environment.
4.50. For the objective of engineering design and style, the linear connection among the pollution flashover voltage and the altitude is a lot more convenient additionally, the descending slope k has an explicit physical significance, thereby reflecting the effect of altitude on pollution flashover voltage additional expressly.
Outlines and structural dimensions of an insulator should really be decided depending on mechanical efficiency and electric overall performance of such an insulator, hydrophobic capacity, and antipollution capacity of the insulation surface and compatibility with specified connecting components.
Significant issue faced by electrical utilities in the higher voltage energy transmission line is the flashover due to polluted insulators, which final results in power outages, waste of time and funds, bring about frustration to prospects, equipment harm and potentially, catastrophic fires.
In this case, the test shall be performed in the following sequences: apply voltage to the polluted insulator extract air till the atmospheric pressure in the artificial climate chamber reaches the designated level wet the insulator with steam fog till the end of the flashover or withstand test.
