Lühisvoolud

Lühisvoolud, also known as short circuits, are unintended low-resistance paths that allow electric current to bypass the normal circuit. This bypass causes a sudden and often dramatic increase in the current flowing through the circuit. Lühisvoolud can occur for a variety of reasons, including damaged insulation, faulty wiring, or the accidental bridging of electrical contacts by conductive materials.

The consequences of a lühisvool can be severe. The rapid surge in current generates a significant amount of heat, which can lead to melting of wires, damage to electrical components, and even fire. In extreme cases, the immense energy released can cause explosions. Therefore, electrical systems are equipped with protective devices such as fuses and circuit breakers, designed to detect and interrupt lühisvoolud before they can cause extensive damage or pose a safety hazard. These devices work by sensing the abnormally high current and quickly opening the circuit, thereby stopping the flow of electricity. Understanding the causes and implications of lühisvoolud is crucial for electrical safety and the proper maintenance of electrical installations.
