What Are The Reasons For The Failure of The Green Child?

Pulished on Feb. 12, 2019

On-line inspection of insulator such as the Standard Glass Insulator faults and timely processing of fault points can effectively prevent such accidents. Let's first analyze the cause of the green fault.

First, the cause of the failure of the green child

(1) Lightning strike or failure caused by external force

According to statistics, in the green line fault of transmission lines, the fault caused by lightning strikes accounts for 50% to 55% of the total.

(2) The insulation causes the insulator such as the Suspension Insulators to malfunction.

In the natural environment, due to the influence of sulfur dioxide, nitrogen oxides and particulate dust, a layer of pollutants is deposited on the surface of the green seeds.

(3) Failure caused by bird damage

Ming class excrement has an effect on the absolute effect.

(4) The aging causes the insulator such as the Aerodynamic Glass Insulator to malfunction

(5) Failure caused by low resistance

One or several pieces of absolute green strength in the insulator string are reduced.

(6) Failure caused by overvoltag
