jännitevaihtelua
Jännitevaihtelu, also known as voltage fluctuation or voltage variation, refers to the deviation of the electrical supply voltage from its nominal or intended value. This deviation can manifest as an increase (overvoltage) or a decrease (undervoltage) in the voltage level. These fluctuations can occur over various time scales, from momentary sags and swells to longer-term drifts.
The causes of jännitevaihtelu are diverse. On the supply side, they can stem from faults in the
The effects of jännitevaihtelu can range from negligible to severe. Sensitive electronic equipment, such as computers,
Mitigating jännitevaihtelu often involves measures at the source of the problem, such as improving power grid
