A template is a device used by sanctioning body officials to check the body shape and height of racing vehicles. [1] The template is used to check that teams have manufactured the sheet metal used in the vehicle bodies to within tight tolerances (up to thousandths of an inch).
A conventional six-winding, grounding transformer or zigzag bank, [1] with the same winding and core quantity as a conventional three-phase transformer, can also be used in zigzag winding connection. In all cases the first coil on each zigzag winding core is connected contrariwise to the second coil on the next core.
A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. [1] Examples include electronic instruments and motor vehicles. Usages
However, in transmitting antennas the ground system carries the full output current of the transmitter, so the resistance of an inadequate ground contact can be a major loss of transmitter power. Medium to high power transmitters usually have an extensive ground system consisting of bare copper cables buried in the earth under the antenna, to ...
Electrical equipment may be designed with a floating ground for one of several reasons. One is safety. For example, a low-voltage DC power supply, such as a mobile phone charger, is connected to the mains through a transformer of one type or another, and there is no direct electrical connection between the current return path on the low-voltage side and physical ground (earth).
In a TN (terra–neutral) earthing system, one of the points in the supply transformer is directly connected with Earth, usually the neutral-star-point in a star-connected supply transformer, the same point from which a neutral (N) connection would be provided. Exposed-conductive-parts within a consumer installation are connected with Earth via ...
When a car moves over the ground, the boundary layer on the ground becomes helpful. In the reference frame of the car, the ground is moving backwards at some speed. As the ground moves, it pulls on the air above it and causes it to move faster. [dubious – discuss] This enhances the Bernoulli effect and increases downforce.
The diagram shows leakage current from an appliance such as an electric motor A flowing through the building's ground system G to the neutral wire at the utility ground bonding point at the service panel. The ground loop between components C1 and C2 creates a second parallel path for the current. [8]
