This template adds the voltage of the electrification system of a rail system in a consistent way. Template parameters [Edit template data] Parameter Description Type Status fraction frac If ''y'', gives the pre-1995 format of 11 kV 16+2⁄3 Hz AC, with the frequency as a harmonic of 50 Hz, rather than the modern frequency 11 kV 16.7 Hz AC. String optional The above documentation is ...
Rural electrification systems tend to use higher distribution voltages because of the longer distances covered by distribution lines (see Rural Electrification Administration). 7.2, 12.47, 25, and 34.5 kV distribution is common in the United States; 11 kV and 33 kV are common in the UK, Australia and New Zealand; 11 kV and 22 kV are common in ...
For example, a 100 miles (160 km) span at 765 kV carrying 1000 MW of power can have losses of 0.5% to 1.1%. A 345 kV line carrying the same load across the same distance has losses of 4.2%. [25] For a given amount of power, a higher voltage reduces the current and thus the resistive losses.
The 735 kV power line is said to lessen the environmental impact of power lines, as one single power line operating at this voltage carries the same amount of electric power as four 315 kV power lines, which would require a right-of-way wider than the 80.0–91.5 metres (262.5–300.2 ft) [29] [30] width required for a single 735 kV line.
The Shenyang trolleybus electrocution accident is an overhead power line electrocution accident involving public transport in Shenyang, the capital city of Liaoning province, Northeast China. The accident happened at 15:50 on August 12, 1998, when a trolley pole on a trolleybus stopping at a bus stop in the central Shenhe District slipped off ...
For example, in the United States, the most common voltage is 12.47 kV, with a line-to-ground voltage of 7.2 kV. [7] It has a 7.2 kV phase-to-neutral voltage, exactly 30 times the 240 V on the split-phase secondary side.
The voltage changes due to the transition from line-to-line to line-to-earth, typically reducing a 22 kV grid to 12.7 kV SWER or a 33 kV grid to 19.1 kV SWER. The SWER line is a single conductor that may stretch for tens or even hundreds of kilometres, with a number of distribution transformers along its length. At each transformer, such as a ...
