An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
Grid units will always be energized on the top side from the many other units tied into the grid. A spot network is 2 or more transformers dedicated to a single customer. The grid feeds multiple customers. A network protector has a circuit breaker set of contacts and a controlling protection relay. The components are enclosed in a protective ...
Diagram of a simple electrical cable with three insulated conductors, with IEC colour scheme. About 1950, PVC insulation and jackets were introduced, especially for residential wiring. About the same time, single conductors with a thinner PVC insulation and a thin nylon jacket (e.g. US Type THN, THHN, etc.) became common. [citation needed]
Selectivity, also known as circuit breaker discrimination, is the coordination of overcurrent protection devices so that a fault in the installation is cleared by the protection device located immediately upstream of the fault. The purpose of selectivity is to minimize the impact of a failure on the network.
It is a fully owned subsidiary of General Electric (GE Energy). Kelman's DGA division was acquired by GE in August 2008 for $50M [1] and the company's product line became part of GE Energy's Transmission & Distribution Automation business.
GE diagram of a turbine locomotive. Union Pacific operated the largest fleet of gas turbine–electric locomotives (GTELs) of any railroad in the world. The prototype, UP 50, was the first in a series built by General Electric for Union Pacific's long-haul cargo services and marketed by the Alco-GE partnership until 1953. The prototype was ...
