SUB STATION An intermediate electricity-distributing location from which electrical energy is transformed and transmitted to users within a given geographical area. GRID STATION It is a station where multiple inputs/outputs comes and goes , where the voltage is transformed as it is required.

What is a vacuum tube that contains a grid called?
one grid - triodetwo grids - tetrodethree grids - pentodefour grids - hexodefive grids - heptode, pentagrid convertersix grids - octodeseven grids - nonodeetc.
How does a vacuum tube work?
contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the anode. Adding one or more control grids within the tube allows the current between the cathode and anode to be controlled by the voltage on the grids.[5]
What are the important of electrical energy?
The electric power system or power grid are very important in maintaining the electricity for the country. Grids are divided geographically. Power issues can manifest in the grid resulting in brown-outs and black-outs.
What are grid failure reasons in power system?
Grids collapse due to two basic reasons. One is the failure of the equipment, like it happened a decade ago in 2002 when the northern grid collapsed, due to fog/pollution. The second trigger is power suppliers drawing excessive power from the grid. Which results in the balance of power generation and supply goes haywire with a cascading effect. This is probably the reason why the grid failed
What would make the plate of a vacuum tube glow bright red?
That bright red color is heat: infrared energy and visible light. The electrons gain kinetic energy as they accelerate away from the Cathode. As each electron is absorbed into the metal Plate, its kinetic energy becomes acoustic motion in the Plate's atoms - heat. (The plate is being hammered.)It is not normal for vacuum tube circuits to operate at high Plate temperatures that are this conspicuous. This circuit has an excessive product of Plate voltage times Plate current, and/or the vacuum tube Grids are biased incorrectly.One common technique for reducing this heating effect is to use a second Grid near the Plate that is biased much more positive than the Plate. This causes the electrons to decelerate between Grid 2 and the Plate - loosing most of their kinetic energy before absorbtion.
Are the two grids in the stinger bug zapper conected together?
The two grids are not connected together. There is a high voltage difference between the two grids. When the bug tries to crawl through the grids to get to the light, it completes the circuit and the electricity passes through the bug. The electricity is what kills the bug.
What is the difference between a grid and a micro grid?
The difference between smart grids and smart microgrids is scale, the types of decision makers and the potential rate of change. While smart grids take place at the utility and national grid level, involving the large transmission and distribution lines, smart microgrids are smaller scale, require fewer decision makers and have faster implementation.

Can you accurately find a diagonal distance on a grid by only counting the grids between them?

What has the author John W Slater written?
John W. Slater has written: 'An approach for dynamic grids' -- subject(s): Computational fluid dynamics, Computational grids, Euler-Lagrange equation, Finite difference theory
What are map for?
the map grids are the grids that are on the map for the earth to be measured.
What is the ratio of corresponding sides in two grids?
There is none, since there are no grids!
Why do archaeologist create grids?
Archaeologists create grids because it makes it easier for them to measure where things were found, and where they have dug. Without grids it would be easy to become confused.
How many ohms is a low resistance?
This is relative to the purpose or application. 1 mega ohm may be considered "low resistance" when testing insulation levels; when testing a cable, 1 ohm may be too much. When testing substation ground grids, I believe 1 ohm is the maximum allowable value in some countries.
What is the difference between the first white exogrid baseball bat and the new 2010 exogrid baseball bat?
the white exo is and has been the best exo that tpx has made so far. i have used all of them and i currently have the white one. it has much more pop than any of the other exo grids. that's the only difference.
How do smart grids differ from the current electricity infrastructure in the US?
smart grids are different from the existing infrastructure in the united states because it is much capible to destribute electricity more efficiently and of allowing communications between the various systems of the grid, and they also provide the consumer the detail of there usage and guide them how to reduce there consumption because they exist on modern technology. but the other old existing infrastructure is based on old technology, they have there old destribution plan, line losses and not able to know the usage of every consumer and the peak hours of usage like the smart grids that's why the reason smart grids are better then old electricity infrastructure.
