Causes of power system failure
Top 6 Causes for power system failures 1- Underground cables Electrochemical treeing of underground power cables is one of the alarming causes for the downscaling of power system reliability. Treeing is a process in which the dielectric strength of an insulating material perishes as a result of moisture penetration while the electric field is still in operation.Once the dielectric strength of the insulating material weakens considerably, a lightning strike or even a switching can destroy the insulation. Solution for this is one can considerably reduce electrochemical treeing by installing surge protection devices on the electric poles, which are capable of transitioning voltage transients into the ground. Alternatively, one can also purchase cables that are treeing resistant. 2-Transformer breakdowns Transformers are one of the most important components of a distributed power system and can pose a lot of complicacies if they breakdown. Though voltage transients and faults can impose
