kõrgevoltu

Kõrgevoltu is an Estonian term that translates to "high voltage" in English. It refers to electrical systems that operate at a significantly higher potential difference than those typically found in household or low-voltage applications. The exact threshold for what constitutes "high voltage" can vary depending on the specific context and regulations, but it generally begins at several thousand volts.

High-voltage systems are essential for the efficient transmission and distribution of electricity over long distances. Power generated at power plants is stepped up to very high voltages using transformers to minimize energy loss during transmission through power lines. Before reaching consumers, this voltage is then progressively reduced at substations and local transformers to safer, usable levels for homes and businesses.

Common applications of high voltage include power transmission grids, industrial machinery, high-power lighting systems, and certain scientific research equipment. Due to the inherent dangers associated with high voltage, strict safety protocols, specialized equipment, and trained personnel are always required when working with or near these systems. Accidental contact with high voltage can be lethal, making safety a paramount concern in its handling and management.
