Genomgångsfel

Genomgångsfel, often translated as "pass-through error" or "through-fault," is a concept primarily found in electrical engineering and power systems. It refers to an undesirable event where a fault current, instead of being interrupted or contained by protective devices, continues to flow through a component or a part of the system that is not designed to handle such a high current for an extended period.

This can occur due to various reasons, including malfunctioning protective relays, incorrect settings of circuit breakers, or improper coordination between different protective devices. When a genomgångsfel happens, the component experiencing the fault can be severely damaged due to excessive heat, mechanical stress, or electromagnetic forces. This damage can lead to cascading failures, where the initial genomgångsfel triggers further faults in connected equipment, potentially causing widespread power outages.

Preventing genomgångsfel involves meticulous design of protection schemes, regular testing and maintenance of protective devices, and ensuring proper grading and coordination of these devices. Accurate fault current calculations and adherence to relevant standards are also crucial in minimizing the risk of such events and ensuring the reliable operation of electrical power systems. The consequences of a genomgångsfel can range from minor equipment damage to catastrophic system collapse, highlighting its significance in power system protection.
