Control Panels-What the books don't tell you...

Hello guys,

If y'all haven't read the previous post click on the links below:

1)https://electricalmaniacs.blogspot.in/2017/09/electrical-control-panels- interesting.html
2)https://electricalmaniacs.blogspot.in/2017/09/detailed-study-of-electrical-control.html

In the previous post we understood somethings about the control panels sans any book or anything,we just used our basic electrical engineering knowledge.

Now, start by typing "control panel" in google or open the first page of your book and just read the first page.This is what I got.!

"Control panel is a cabinet which contains electrical components to control the motors and equipment".

From this one line only we can understand that control panel is a cabinet that contains electrical equipment (why only electrical equipment,why not mechanical or thermal or some other?/Which electrical equipment?/Why that particular equipment only,what is its importance?)

Then comes..

"A control panel is a flat, often vertical, area where control or monitoring instruments are displayed or it is an enclosed unit that is the part of a system that users can access, as the control panel of a security system (also called control unit).

They are found in factories to monitor and control machines or production lines and in places such as nuclear power plants, ships, aircraft and mainframe computers. Older control panels are most often equipped with push buttons and analog instruments, whereas nowadays in many cases touchscreens are used for monitoring and control purposes".

Questions:

1. Why is the control panel flat or vertical (any specific reason!)?
2. What are control and monitoring equipment?
3. Why are the panels enclosed?
4. Why are they used only in factories,why not in our houses?

One more...

"Electrical control panels control equipment. They include power, control and operator devices that allow an operator to control a piece of equipment. Electrical control panels are used to control every piece of equipment in every industry."

Questions:

1. What are power,control and operator devices?
2. What is the role of operator while using control panels?

These are some of the questions that came into my mind, there may be many more feel free to add them in comments.

These are just the questions and I know most of them are stupid.Most of the times it is those stupid questions,that help us understand the real problem. Try to get some answers to them, in the process of getting answers you will learn a lot more i promise you that.

Also I am not asking you guys any questions , giving you a rather new perspective of understanding a topic(according to me).

Cheers.!!

Keep asking why...

Till the next post...
