strømstigning

Strømstigning, also known as voltage surge or voltage spike, is a sudden increase in the voltage of an electrical system. It is a transient phenomenon that can occur due to various reasons, including switching operations, lightning strikes, and faults in the electrical network. Strømstigning can have significant impacts on electrical equipment and systems, potentially causing damage or malfunctions.

The duration of a strømstigning is typically very short, ranging from a few microseconds to a few milliseconds. However, the high voltage levels during this period can be detrimental to sensitive electronic devices. Strømstigning can be categorized into two main types: impulsive and oscillatory. Impulsive surges are characterized by a rapid rise and fall, often caused by lightning strikes or switching operations. Oscillatory surges, on the other hand, have a more gradual rise and fall, often resulting from faults in the electrical network.

To mitigate the effects of strømstigning, various protective measures can be implemented. Surge protectors, also known as transient voltage surge suppressors (TVSS), are commonly used to divert excess voltage away from sensitive equipment. Grounding systems can also help to dissipate excess voltage safely. Additionally, proper insulation and maintenance of electrical equipment can reduce the risk of strømstigning.

Strømstigning is a critical consideration in the design and operation of electrical systems, particularly in environments where sensitive electronic equipment is used. Understanding the causes, characteristics, and protective measures associated with strømstigning is essential for ensuring the reliability and safety of electrical systems.
