Synopsis A sulfur hexafluoride (SF6) circuit breaker uses contacts surrounded by sulfur hexafluoride gas to quench the arc. They are most often used for transmission-level voltages and may be incorporated into compact gas-insulated switchgear. .....
SynopsisProgrammable power supplies are sometimes called "system" power supplies, as they are often used as part of a computer-operated system for testing or production. A DC power supply is one that supplies a constant DC voltage to its load. Depending on its d.....
SynopsisSubmarines need large amounts of electricity to operate safely under water. They charge their batteries using diesel or nuclear-driven generators. Diesel subs must surface to recycle their batteries because carbon monoxide fumes are deadly. Nuclear ones can re.....
Synopsis The role of the low voltage power distribution system in a building of any kind is to receive electrical power at one or several supply points and to deliver it to individual electrically operated devices. The importance of the power distribut.....
DIN guideway power supplies are based on a series of standard guideway power supplies created by the German Institute for Standardization (DIN), Germany's national standards organization. This power supply converts alternating current (AC) to direct current (DC) at various.....
SynopsisLead-Acid battery uses a chemical reaction to do work on charge and produce a voltage between their output terminals. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, its ability to supply high surge currents means that the ce.....
SynopsisSelf-propelled jack-up vessel is a vessel specifically designed for the installation of offshore wind turbines. Similar to a jack-up rig it is self-elevating. To enable quick relocation in the wind farm it is self-propelled. It also has a slender ship shaped h.....
SynopsisA DC-to-DC converter is a class of power supply which converts a source of direct current (DC) from one voltage level to another. They can essentially step-up, step-down or invert a DC voltage. The global DC-DC Power Supplies market was valued at US$ 851.....
Synopsis Hybrid energy systems consist of both of solar PV panels and wind generators. These two types of renewable energy products are often considered wind-solar hybrid systems. The advantages offered is that they are able to capture renewable energy.....
Synopsis Graphene is a one-atom-thick sheet of carbon atoms with a relative surface area of 2,630 m2/g, which is superior at storing charges with almost no degradation over long-term cycling. The bonds in graphene give graphene more than four times the.....
