jordfejlstrøm
Jordfejlstrøm, also known as earth fault current, is an electrical current that flows through the earth when there is a fault in an electrical system. This type of current is typically the result of a live conductor coming into contact with the earth or a conductive object. The primary purpose of jordfejlstrøm is to activate protective devices, such as residual current devices (RCDs) or earth fault protection devices, which are designed to detect and interrupt the fault current to prevent electrical shock and fires.
The magnitude of jordfejlstrøm is influenced by several factors, including the impedance of the earth, the
Proper management of jordfejlstrøm is crucial for ensuring the safety and reliability of electrical systems. This
