Ylijännitetorjuntajärjestelmä
Ylijännitetorjuntajärjestelmä, often translated as surge protection system, is a crucial component in electrical and electronic systems designed to safeguard against transient overvoltages. These overvoltages, also known as surges or transients, are sudden, short-duration increases in voltage that can far exceed the normal operating level of a system. They can be caused by various sources, including lightning strikes, switching operations within the power grid, and electrostatic discharge.
The primary function of an ylijännitetorjuntajärjestelmä is to detect these abnormal voltage spikes and divert the
Common types of SPDs include metal oxide varistors (MOVs), transient voltage suppressors (TVS diodes), and gas
