Although this is more hazardous for personnel than working on electrical equipment with the power off, live-line maintenance techniques are used in the electric power distribution industry to avoid the disruption and high economic costs of having to turn off power to customers to perform essential periodic maintenance on transmission lines and ...
The Trans Bay Cable is a high-voltage direct current (HVDC) underwater transmission cable interconnection between San Francisco, California and Pittsburg, California. [1] The 53 mi (85 km) cable under San Francisco Bay and through the Carquinez Strait can transmit 400 megawatts of power at a DC voltage of ±200 kV, enough to provide 40% of San Francisco's peak power needs.
The Bay–Calamba–Biñan Transmission Line (abbreviated as 8LI1BIN-CAA, 8LI2BIN-CAA, 8LI1CAA-BYZ, 8LI2CAA-BYZ, BCBTL), formerly known as Bay–Biñan Transmission Line, is a 230,000 volt, double-circuit, two-part transmission line in Calabarzon, Philippines that connects Bay and Biñan substations of National Grid Corporation of the Philippines (NGCP).
A charging station, also known as a charge point, chargepoint, or electric vehicle supply equipment (EVSE), is a power supply device that supplies electrical power for recharging plug-in electric vehicles (including battery electric vehicles, electric trucks, electric buses, neighborhood electric vehicles, and plug-in hybrid vehicles).
The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power ...
Getrag (German: [ɡəˈtʁaːk]), stylized as GETRAG, [a] was a major supplier of transmission systems for passenger cars and commercial vehicles. The company was founded on 1 May 1935, in Ludwigsburg, Germany, by Hermann Hagenmeyer; [1] as the Getriebe und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KG.
Pre-charging is commonly used in battery electric vehicle applications. The current to the motor is regulated by a controller that employs large capacitors in its input circuit. [ 1 ] Such systems typically have contactors (a high-current relay ) to disable the system during inactive periods and to act as an emergency disconnect should the ...
A smart battery requires a smart charger. Some smart chargers can also charge "dumb" batteries, which lack any internal electronics. The output current of a smart charger depends upon the battery's state. An intelligent charger may monitor the battery's voltage, temperature or charge time to determine the optimum charge current or terminate ...
