Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

Incl. Deux-Montagnes line that was built by CNoR in 1918 as 2400 V DC, converted to 3000 V DC in the 1980s, converted to 25 kV 60 Hz in 1995 by ARTM, being converted to light-metro standard and 1500 V DC Ottawa: O-Train: Confederation Line only; the Trillium Line is diesel LRT. China: Beijing: Beijing Subway: Lines 6, 14 and 16: Changchun ...
DC power connectors come in a wide variety of shapes and sizes, and there is unfortunately little standardization to their use. This is a large enough problem that some of the connectors that do have well-defined specifications are frequently used contrary to those specifications.

The type 15 plug and socket has 3 round pins of 4 mm diameter, plus 2 flat pins (for L2 and L3). It is designed for three phase applications and is rated at 10 A, 250 V/440 V. The socket will also accept types 11 and 12 plugs, and the Europlug. The type 25 plug and socket has 3 rectangular pins, 4 mm x 5 mm, plus 2 flat pins (for L2 and L3).
The test explosions codenamed Ruth and Ray used in the core uranium hydride. Ruth used the hydrogen isotope protium (1 H) and Ray used the hydrogen isotope deuterium (2 H or 2 D) as neutron moderators. The predicted yield was 1.5 to 3 kt TNT for Ruth and 0.5-1 kt TNT for Ray, however the tests produced only a yield of about 200 tons of TNT.
Murraylink is an Australian high voltage direct current electricity transmission link between Berri in South Australia and Red Cliffs in Victoria, connecting the two state electricity grids. Murraylink was commissioned in 2002 and is believed to be the world's longest underground transmission system and cost more than A$ 177 million.
In North America and northern South America, it is usually 120 volts, 60 hertz (Hz), but in Europe, Asia, Africa, and many other parts of the world, it is usually 230 volts, 50 Hz. [2] Aircraft often use 400 Hz power internally, so 50 Hz or 60 Hz to 400 Hz frequency conversion is needed for use in the ground power unit used to power the ...
