virransyöksyjä
Virransyöksyjä, a Finnish term, translates to "current surges" or "power surges" in English. It refers to a sudden, temporary increase in voltage within an electrical circuit. These surges can originate from various sources, both internal and external to a building's electrical system. Common external causes include lightning strikes, which can induce powerful voltage fluctuations, and switching events on the power grid, such as those caused by utility work or the activation of heavy machinery. Internal causes can include the operation of high-power electrical appliances, particularly those with motors, when they are switched on or off.
The effects of virransyöksyjä can range from negligible to highly damaging. Minor surges may go unnoticed,
