Ylijännitteitä
Ylijännitteitä, often translated as overvoltages, are temporary increases in voltage above the nominal or intended level within an electrical system. These events can be caused by a variety of factors, both internal and external to the power grid.
One common cause of ylijännitteitä is lightning strikes. When lightning hits a power line or nearby structure,
Internal to a system, faults or short circuits can also lead to temporary overvoltages as protective devices
Ylijännitteitä can pose a significant threat to electrical equipment. Sensitive electronic components, insulators, and even larger
To mitigate the risks associated with ylijännitteitä, various protective measures are employed. Surge arresters, also known
