Ground (electricity) - Wikipedia, the free encyclopedia (793 words) |
 | The ground wire is also usually bonded to pipework to keep it at the same potential as the electrical ground during a fault. |
| This signal ground may or may not actually be connected to a power ground. |
| During dry weather, the ground connection often developed a high resistance, requiring water to be poured on the ground rod to enable the telegraph to work or phones to ring. |
| Ground (electricity) (515 words) |
| An electrical connection to earth via an earth-electrode which can be as simple as a metallic ground rod or stake driven into the earth, a connection to buried metal water piping, or an extensive system of buried rods and wires. |
| In an electrical circuit, a common return path that usually (a) is connected to an earth-electrode subsystem and (b) is extended throughout a facility via a facility ground system consisting of the signal reference subsystem, the fault protection subsystem, and the lightning protection subsystem. |
| Grounding is primarily used for safety to prevent electric shock or fires started from a voltage potential existing between the earth and a conductor such as an appliance cabinet or chassis. |
