Railway electrification systems using alternating current (AC) at 25 kilovolts (kV) are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60 Hz), which simplifies traction substations. The development of 25 kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for ra. HistoryMany trial sites were developed at the beginning of the 20th century but developing a main frequency. .
Electric power for 25 kV AC electrification is usually taken directly from the three-phase . At the transmission substation, a step-down is connected across two of the three phases of the high. .
Railway electrification using 25 kV, 50 Hz AC has become an international standard. There are two main standards that define the voltages of the system: • EN 50163:2004+A1:2007 – "Railway application. .
The 2 × 25 kV system is a system which supplies 25 kV power to the trains, but transmits power at 50 kV to reduce energy losses. It should not be confused with the 50 kV syste. .
Systems based on this standard but with some variations have been used. In Japan, this is used on existing railway lines in , , and , of which Hokuriku and Kyush.

How many b/d does Venezuela refine?
According to IPD Latin America estimates, Venezuela's refinery throughput has been less than 300,000 b/d, or roughly one-fifth of its nameplate capacity.17 Venezuela has worked with Iran to supply fuel as well as refining materials, spare parts, and technicians to restart the refineries.
How much oil does Venezuela produce in 2023?
Despite the sizeable reserves, Venezuela produced 0.8% of total global crude oil in 2023. Most of Venezuela's proven oil reserves are extra-heavy crude oil from the Orinoco Belt.
Will Chevron be able to produce crude oil in Venezuela?
Much of Venezuela's crude oil production capacity and infrastructure have suffered from a decade-long lack of capital and regular maintenance. Chevron's earlier exemption increased its production to 135,000 barrels per day (b/d) in 2023, and we expect Chevron's output in Venezuela to reach 200,000 b/d by the end of 2024.
How many refineries are in Venezuela?
Of Venezuela's six refineries, only five remain operational, all running at no more than 20% of total capacity. The country's aging refining system, plagued by frequent shutdowns and low output, has deteriorated after years of underinvestment, poor management and international sanctions that have limited access to spare parts.
