jännitevalaistus

Jännitevalaistus, often translated as voltage lighting or high-voltage lighting, refers to lighting systems that operate at significantly higher voltages than standard household circuits. Typically, this means voltages above 1000 volts AC or 1500 volts DC, although the term can sometimes encompass lower high voltages depending on the specific application and context. These systems are not typically found in residential settings due to safety regulations and practical considerations.

The primary advantage of jännitevalaistus lies in its ability to reduce current for a given power output. Lower current means thinner and less expensive wiring can be used over long distances, and less energy is lost as heat due to electrical resistance. This makes it suitable for large-scale applications where power needs to be transmitted efficiently.

Common applications for jännitevalaistus include industrial facilities, large commercial buildings, outdoor area lighting such as sports fields or extensive roadways, and specialized applications like tunnel lighting or temporary construction site illumination. The equipment used in these systems, including transformers, switchgear, and luminaires, is designed to safely handle the higher voltages. Installation and maintenance require specialized training and adherence to strict safety protocols due to the increased risk of electrical shock.
