Korkeajännitteen

Korkeajännitteen is a Finnish term that translates to "high voltage" in English. It refers to electrical systems or installations that operate at elevated potential differences. The specific voltage levels considered "high" can vary depending on the context and industry standards, but generally, it implies voltages significantly above those found in typical household electrical outlets.

High voltage is commonly used in power transmission and distribution networks to efficiently transport electricity over long distances. The higher the voltage, the lower the current needed to transmit the same amount of power, which in turn reduces energy losses due to resistance in the transmission lines. Consequently, this minimizes the need for thicker, more expensive conductors.

Examples of high voltage applications include the main power lines that carry electricity from power plants to substations, as well as the lines that distribute power within communities. Specialized equipment, such as transformers, switchgear, and insulators, are designed to safely handle and manage these high voltage levels. Working with or near high voltage systems requires strict safety protocols due to the significant risk of electrical shock, arc flashes, and other hazards.
