Interpretation of Schematic Diagram

I'm sorry. What does an electrical engineer know how to do?

Since you say, "I'm not so good in reading/interpreting a schematic diagram.. specially on circuit breakers diagrams and other complicated diagrams."

I'd be interested in knowing what it is you can do. Maybe some part of your education is still retained in your brain?

Help us, help you.

It is virtually impossible to be an electrical engineer and yet be unable to interpret a circuit diagram. It should be impossible to get through school without being able to read circuit diagrams. How could you possibly analyze a circuit without using a schematic?

Do you have a different meaning for "electrical engineer"? In many countries, an electrical engineer is responsible for designing electrical circuits. Are you perhaps an apprentice maintenance worker?

I would like to know a few things here myself. First, if you think that a circuit breaker schematic diagram is a complicated diagram I'd like to know why?

I would expect that any electronic technician could fabricate a circuit with a circuit breaker diagrammed.

I would expect any certified electrician to properly fabricate the building wiring including circuit breakers to meet local building codes.

I would expect that a degreed electrical engineer would be able to fabricate a schematic that included a circuit breaker and to be able to explain the physical principles that determine how a circuit breaker works. I would expect that any degreed engineer could fairly quickly figure out from his schooling the advantages and drawbacks of a magnetic, thermal or magnetic/thermal circuit breaker even if they never took a class in power distribution.

I would expect a professionally licensed electrical engineer could present all the credentials of his formal training to support his analysis of a circuit that contained a circuit breaker to support or refute that all of the appropriate components was or was not properly used in a court of law.

I would like to know what level of an electrical engr. you think you are?

Since circuit breakers are too complicated for you, I was wondering if you could tell us if this non-circuit breaker schematic is too complicated for you. It is identified as a Butterworth filter, but I wonder if you can tell me if this is a bandpass, high-pass or low-pass filter?

As a bonus question, can you derive the transfer function of this circuit?

As an extra bonus question, is it accurate to call this a Butterworth filter? If it is a Butterworth filter what makes it a Buterworth filter? If not why?

I will admit that my last questions are analog design questions. But they do not include a circuit breaker.

There is only one technique, that is "Go back to school and study again". Alternatives are resign the job and dont try to read/ interpret with any schematic diagram...it is very complicated.

All of you should go back to school to review your engineering ethics. Shame on all of you. A guy is stuck and you guys are using your arrogance to cover up your ignorance. If you knew you would have explained it to him or at least directed him.

My suggestion is to take one of the breaker schematics and discuss it with your professor or a colleague considering all design options imbedded into the schematic. Ask him about trip/close ckt, what are the permissive devices, what is the design intent, etc. the key is to know your system very well, devices available and how do you want system to work. Develop a block diagram and engage others in the thought process. After this all future designs will be relatively easy. Remember this is not a "rocket science" and I don't know what these guys are boosting about, a couple of wires, knobs and bulbs??? Anyone can do this.

There is no stupid question but there are snobby engineers who think they know everything and who came out of the womb with a degree. Shame!

What absurd doggerel. Anyone who claims to be an electrical engineer has to be able to read a schematic, or at the very least be able to clearly communicate why a part of a schematic baffles them.

Now as far as ethics, guest(?), how can one who hides in the shadows claim to show ethics.

As far as your high standard of "rocket science" allow me to remind you that the control system of a guided rocket is a well designed electrical system. The rocket scientist relies on the electrical engineer's capability to design and fabricate the closed loop feedback system that controls the rocket.

Now some have already argued that there is no stupid question (an opinion I disagree with) but the question asked by the OP was not a stupid question at all. It was insulting! To ask a question "How to interpret a schematic?" while claiming to be an electrical engineer was highly insulting to anyone who earned an electrical engineering title or degree. This is like somebody claiming to be a dentist and asking where the bicuspids are in the human mouth.

Good am. I respect all of your Insights. But I just want to emphasize, that i'm not asking How to interpret schematic diagram?, rather, the techniques in interpreting them, for the reason that i can interpret schematic diagram(basic/simple), except those complicated diagram w/c i hav'nt encounter during college days. Yes, its a shame on an Electrical engr. who don't know how to read/interpret a schematic diagram.

Thanks. More Power and God Bless us All!
