kortslutningen

Kortslutningen, often translated as a short circuit, is an electrical fault that occurs when an unintended low-resistance path is created between two points in an electrical circuit that are normally at different potentials. This bypasses the intended load, allowing a large current to flow. This excessive current can cause overheating, melting of insulation, fires, and damage to electrical equipment.

The most common causes of short circuits include damaged insulation on wires, faulty wiring, or the accidental contact of conductive materials with electrical terminals. For example, frayed wires can touch each other, or a metal object might fall across exposed terminals. In electronic devices, component failure can also lead to a short circuit.

Protective devices are designed to mitigate the risks associated with short circuits. Fuses and circuit breakers are the most prevalent. When a short circuit causes current to exceed a safe limit, a fuse will blow, breaking the circuit, or a circuit breaker will trip, opening the electrical pathway. These devices are crucial for preventing fires and protecting expensive electrical systems. Understanding and preventing short circuits is a fundamental aspect of electrical safety and maintenance.
