SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".
In electric power, a bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it. Bushings are typically made from porcelain, though other insulating materials are also used.
The high-voltage primary windings are brought out to bushings on the top of the case. Single-phase transformers, generally used in the North American system, are attached to the overhead distribution wires with two different types of connections: Wye – A 'wye' or 'phase to neutral' transformer is used on a wye distribution circuit.
An automobile auxiliary power outlet (also known as car cigarette lighter or auxiliary power outlet [1]) in an automobile was initially designed to power an electrically heated cigarette lighter, [1] but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile directly from the ...
Electrical treeing first occurs and propagates when a dry dielectric material is subjected to high and divergent electrical field stress over a long period of time. . Electrical treeing is observed to originate at points where impurities, gas voids, mechanical defects, or conducting projections cause excessive electrical field stress within small regions of the di
Ground communications outlets (GCO) have been installed at some U.S. airports to provide a means for pilots on the ground to communicate with flight service stations and air traffic control (ATC) facilities for the purpose of filing, opening and closing VFR or IFR flight plans; obtaining weather briefings and clearances; and similar communications.
Class O facilities are non-protected outlets and are subject to prolonged outages which may go undetected and unreported. There is also a special variant of RCO which in Canada is called a Dial-up Remote Communications Outlet (DRCO) and in the U.S. is called a Ground communication outlet (GCO). DRCOs and GCOs connect to an FIC or FSS over a ...
