What is the principle of live-line washing for substations?

Why Do Electrical Equipment Need a "Bath"? Due to atmospheric pollution, contaminants accumulate on insulating porcelain insulators and posts. During rain, this can lead to pollution flashover, which in severe cases may cause insulation breakdown, resulting in short circuits or grounding faults. The
