jänniteturppaan

Jänniteturppaan is a Finnish term that translates to "voltage spike" or "voltage surge." It refers to a sudden, brief increase in voltage above the normal operating level in an electrical circuit. These transient events can be caused by various factors, including lightning strikes, switching operations in power grids, or the operation of high-power electrical equipment.

While short-lived, voltage spikes can carry significant energy. This energy can potentially damage sensitive electronic components, leading to malfunctions or complete failure. Devices that are particularly vulnerable include computers, televisions, audio equipment, and other appliances with microprocessors or delicate circuitry.

Protection against jänniteturppaan is often achieved through the use of surge protectors, also known as surge suppressors. These devices are designed to divert excess voltage away from connected equipment. Common forms of surge protection include power strips with built-in surge suppression and whole-house surge protection systems installed at the main electrical panel. Regular testing and replacement of surge protectors are recommended to ensure their continued effectiveness.
