Túlfeszültségvéd

Túlfeszültségvéd is a Hungarian term that translates to "overvoltage protection" in English. It refers to devices and systems designed to safeguard electrical and electronic equipment from damage caused by sudden, excessive voltage surges. These surges can originate from various sources, including lightning strikes, switching operations within the power grid, or faults in electrical systems.

The primary function of túlfeszültségvéd devices is to divert the excess energy away from sensitive equipment and safely dissipate it, typically to the ground. This prevents the voltage from reaching levels that could cause insulation breakdown, component failure, or even complete destruction of connected devices.

Common types of túlfeszültségvéd include surge protectors, which are often found in household power strips, and more sophisticated surge arresters used in industrial and utility applications. The effectiveness of these devices is measured by their ability to absorb and redirect energy, often quantified by joule ratings or voltage clamping levels. Proper installation and selection of túlfeszültségvéd are crucial for ensuring the reliable operation and longevity of electrical infrastructure and electronic devices. Regular inspection and maintenance can also help ensure their continued effectiveness.
