lühivool

Lühivool is an Estonian term that translates to "short circuit" in English. It refers to an abnormal electrical connection that allows current to flow through a path of very low impedance. This bypasses the normal intended path, which typically includes a load. Short circuits can occur due to various reasons, such as damaged insulation, faulty wiring, or improper connections.

The primary characteristic of a short circuit is a rapid and significant increase in current flow. This surge of electricity can lead to a number of detrimental effects. Overheating is a common consequence, as the excessive current generates a large amount of heat due to resistive losses. This can melt insulation, damage components, and even cause fires.

To protect electrical systems from the damaging effects of short circuits, protective devices are employed. Fuses and circuit breakers are the most common examples. When a short circuit occurs, the abnormally high current causes these devices to activate, interrupting the flow of electricity and preventing further damage to the circuit and connected equipment. Understanding and preventing short circuits is crucial for electrical safety and the reliable operation of any electrical system.
