  • Hazards and Safety in High Voltage Power Lines

    Oct 01, 2021 · High voltage transmission lines are overhead power lines used for efficient bulk power transmission. Since the power needs to be transmitted over long distances, the voltage level of transmitted power is increased to reduce the current to minimize I² R i.e., power losses during transmission. The lower the current, the lower the resistive losses in the conductors.
