Analysis of lightning impulse rain flash characteristics and performance enhancement of 35 kV insulator string with zero-value unit

open access: yes电力工程技术
Lightning weather is frequently accompanied by heavy rainfall, resulting in the bridging of the insulator umbrella skirt of the transmission line by rain columns. Under the impact of lightning, the "bridging effect" may occur.

Artificial rain test of outdoor long rod insulators [PDF]

open access: yes, 2009
Due to the decrease of industrial contamination emission nearly the whole territory of Poland belongs to the pollution class light. As a result, the insulators can have now a very short leakage distance.
