What is the primary cause of electrical failures in industrial equipment?

The primary cause of electrical failures in industrial equipment is often attributed to poor connections and insulation degradation. Electrical systems rely heavily on the integrity of their connections and insulation to function properly. Over time, connections can loosen due to thermal expansion and contraction, vibration, and wear, which can lead to arcing, increased resistance, and ultimately failure. Similarly, insulation materials can degrade due to exposure to heat, moisture, and chemicals, compromising their ability to prevent short circuits or electrical leaks.

While overheating components can indeed lead to failures, it is frequently a secondary result of poor connections or degraded insulation, as these issues can increase electrical resistance and generate excess heat. Excessive vibration and noise can also contribute to equipment failure; however, they are more likely to impact mechanical components rather than the electrical systems directly. Inadequate maintenance schedules certainly play a role in the overall reliability of equipment, but it is the specific degradation of connections and insulation that is most directly linked to electrical failures.
