NettetThe overhead line (3) and feeder (5) are on opposite phases so the voltage between them is 50 kV, while the voltage between the overhead line (3) and the running rails (4) remains at 25 kV. Periodic autotransformers (9) divert the return current from the neutral rail, step it up, and send it along the feeder line. Nettet1. okt. 2024 · 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 … NettetAbout. Maintaining power lines, low voltage & high voltage.

"NettetElectricity originally comes out of a power station at a low voltage of around 10-30 kilovolts. It then enters a transmission substation, where it passes through a ‘step-up’ transformer that turns it into high-voltage electricity – up to 400,000 volts. This ensures greater efficiency and less energy loss as it travels around the national grid. " - How much voltage in overhead power lines
