This paper reviews the application of various advanced anti-icing and de-icing technologies
in transmission lines. Introduces the influence of snowing and icing disasters on …

It is found that some composite insulators with faults in transmission lines have no defect
when they are tested in the laboratory, so there is a certain difference between the …

将冰灾造成停电灾难的问题解耦为: 从冰雪到冻雨, 从冻雨到覆冰, 从覆冰到电网故障,
从相继故障到大停电的过程. 冻雨影响输电线故障率的途径涉及冻雨形成的气象规律; …

Atmospheric ice accretion, combined with pollution, has been recognized as a significant
risk factor in the reliability of line and station insulators in cold climate regions. Flashovers …

The effects of surface traps on surface flashover remain controversial. To clarify the relation
between surface flashover and surface trap level, in this work, the surface trap level of epoxy …

Icing flashover of insulator strings has always been a serious factor threatening the safety
and stability of the power grid. Researchers have simulated icing based on an artificial …

During the last 50 years a significant technical advance, namely in our understanding and
control of switching-surge overvoltages, has had some unintended and adverse …

The icing flashover characteristics and discharge processes of 500 kV ac transmission line
long insulator strings energized in the ice accretion were studied. The influence of pollution …

As a result of lightning strikes, pollution, and ice, overhead distribution wires might be short-
circuited and trip. As a result, researchers have developed a new lightning protection …

The energized icing tests for five kinds of 220 kV composite insulators with and without the
grading ring (GR) at the high voltage (HV) end are performed in the artificial climate …
