lühisekatkestuse

Lühisekatkestus refers to a short-circuit interruption in an electrical circuit. This phenomenon occurs when an unintended low-resistance path is created between two points in a circuit that are supposed to have a significant potential difference. This can happen due to damaged insulation, faulty wiring, or foreign objects bridging terminals.

When a short circuit occurs, a very large current flows through the circuit. This excessive current can cause several problems, including overheating of wires, damage to electrical components, and potentially fires. To prevent such damage, electrical systems are equipped with protective devices like fuses and circuit breakers. These devices are designed to detect the abnormally high current and quickly interrupt the flow of electricity, thereby breaking the circuit and preventing further harm.

The term "lühisekatkestus" specifically highlights the interruption that follows a short circuit. It implies that the protective mechanism has successfully operated to stop the dangerous flow of current. Understanding short circuits and their interruption is fundamental to electrical safety and the reliable operation of any electrical system. Regular inspection and maintenance of electrical installations are crucial for minimizing the risk of short circuits.
