Ylijännitteet
Ylijännitteet refers to voltage surges or overvoltages that exceed the normal operating level of an electrical system. These transient phenomena can be caused by various factors, including lightning strikes, switching operations in the power grid, electrostatic discharge, or faulty equipment. Ylijännitteet can have significant negative impacts on electrical and electronic devices, potentially leading to component damage, malfunction, or complete failure. The severity of the damage depends on the magnitude and duration of the overvoltage, as well as the susceptibility of the affected equipment.
To protect against ylijännitteet, various protective measures are employed. Surge protective devices (SPDs), also known as
