Spänningsupptrissningar
Spänningsupptrissningar, a Swedish term, refers to a phenomenon where electrical voltage levels fluctuate unexpectedly. These fluctuations can manifest as either an increase (overvoltage) or a decrease (undervoltage) from the nominal or expected voltage. While minor variations are common in electrical grids, significant spänningsupptrissningar can cause problems for connected equipment.
Overvoltage can occur due to various reasons, including lightning strikes, switching operations in the grid, or
Conversely, undervoltage, often referred to as a brownout, happens when the voltage drops below the standard
The impact of spänningsupptrissningar depends on their magnitude, duration, and the sensitivity of the electrical devices.
