When the pulse of the city - electricity - beats unsteadily due to sudden malfunctions, we always anxiously wait for that 'life-saving' force. Behind the scenes, there is a group of "detectives" working silently, they are cable fault analyzers. What kind of divinity is this? How did they become the "guardians" of power transmission? Today, let's unveil their mysterious veil together.
What is a cable fault analyzer?
Simply put, a cable fault analyzer is like installing a "black box" on complex power cables. When a cable fails, it can record key "accident scene" data and help us accurately locate the fault point. Imagine an underground cable stretching for several kilometers suddenly going on strike, and if the fault point cannot be found, the repair work will be like searching for a needle in a haystack. The existence of analyzers is precisely to end this inefficient and costly search.
The 'culprits' and' accomplices' affecting cable faults
Cable faults are not caused by a single factor, but often the result of multiple factors working together.
Environmental factors such as humidity, high temperature, corrosive soil, and underground biological erosion can all cause damage to the insulation layer of cables.
Mechanical damage: Unexpected compression, puncture, or geological settlement during construction can lead to mechanical fatigue or even damage to cables.
Electrical factors such as long-term overload operation, voltage surges, and insulation aging can accelerate the degradation of cables.
The accumulation of these factors may ultimately lead to various forms of cable faults such as short circuits, grounding, and broken strands.
