Fejlstrøm

Fejlstrøm is a Danish term that translates to "fault current" in English. It refers to an unintended electrical current that flows through a path other than the intended circuit. This can occur due to various reasons, such as insulation failure, damaged wiring, or improper grounding. Fejlstrøm is a critical safety concern in electrical systems as it can lead to electric shock, fires, and damage to electrical equipment.

Different types of fejlstrøm exist, including earth faults (where current flows to the ground) and short circuits (where current flows between conductors). Detecting and mitigating fejlstrøm is essential for electrical safety. This is typically achieved through protective devices like circuit breakers, residual current devices (RCDs), and proper earthing systems. These devices are designed to detect abnormal current flow and quickly interrupt the power supply, thus preventing potential hazards. Regular inspection and maintenance of electrical installations are crucial to minimize the risk of fejlstrøm.
