kortsløringsstrøm

Kortsløringsstrøm, also known as short-circuit current, refers to the extremely high electrical current that flows during a short circuit. A short circuit occurs when an unintended low-resistance path is created in an electrical circuit, allowing current to bypass its intended course. This typically happens when the positive and negative conductors of a power source come into direct contact, or when a live conductor touches ground.

The magnitude of a kortsløringsstrøm is determined by several factors, including the voltage of the power source, the impedance of the circuit, and the characteristics of the fault itself. Because the resistance of the unintended path is very low, Ohm's Law dictates that the current will be very large. This surge of current can have severe consequences.

High kortsløringsstrøm can lead to overheating of wires and components, potentially causing fires. It can also damage electrical equipment and, in extreme cases, lead to explosions. Therefore, electrical systems are designed with protective devices such as fuses and circuit breakers that are rated to interrupt the circuit when the current exceeds a safe level, effectively preventing damage from a kortsløringsstrøm. Understanding and calculating kortsløringsstrøm is crucial in electrical engineering for ensuring the safety and reliability of power systems.
