Terminal Marking of CT

Isn't this covered in your text book?

He doesn't have any!

He's got CR4, he doesn't need any text books.

And I think it leads to some people not wanting to post on these forums b/c they don't want to put up with being belittled for asking a question that some may consider a no brainer, even if the resources aren't easily available elsewhere.

Carry on then,

Cheers.

This is certainly not covered in text book. Text book only give basic principles and theory, this is specific question related to the trade . IMHO, there is legitimate ground for the question, don't you think so?

Can you clarify the question? I'm failing to understand it.

Typically, when using any acronyms, the first time they are used, they need to be spelled out.

CT = Clock Tower?

Cooperate Turd?

Cowardly Turtle?

Cap & Tax?

Cascading Topography?

LOL.. I could go on forever with this nonsense, but I'll save myself some of the embarrassment.

<...LOL...>?

I'm gonna assume the guy is a new grad just starting out at an engineering firm where he has had no proper schooling on the symbology of real electrical equipment like C.T.'s, V.T.'s, GCB's, etc.... Just resistors, caps, inductors, transistors, diodes... Like most all electrical engineers suffer from. If it were in his textbooks, I'd assume he could find it, not that he is too lazy to find it. But rather than just copying what other drawings have done, he's trying to figure out why.

I'm sorry that I do not know the answer to your question coolyaar, but maybe if the above guys would try to help the new guy, rather than make their jokes about how easy something is that they learned decades ago, you would already have the answer.

Well said Pete!

i am referring to current transformers. if some one is not interested in reply to a post, he should not read it instead of passing rubbish comments like LOL , OT , etc.knowledge is meant for sharing .

i have newly joined an R&D firm , but am realy screwed off by the fact that those engineering textbooks gave me nothing for the practical field job.i am in the very start of my job and am engaged in multifields i.e. genset O&M , UPS system handling , switchgear O&M , and above all our own 500 KV grid station. this has diversified my mind and i am a guy with engineering textbooks in my mind that contained just rubbish mathematics and useless formulas.

this forum has helped me a lot and great guys are here for help except a few jokers.

but i really admire the guy on eng-tips.com. they will even answer you how 1+1 is equal to 2 . they know that only those ask questions who know about something and the loosers just laugh.

Hi Msamad, I would have to agre with you, you get my GA.

But do you know what really hacks me off!

Globally we have a brain drain, Companies are not taking on apprentices or training people. We should be encouraging young people to look at working in the electrical field, not by negative comments (not you) that have been said in this forum.

We should help these young minds and nurture them, not scare or shame them!

We should encourage them so that they can reach their full potential and have a better understanding, that they can also pass on to the next generation.

After all they are going to look after us, when we cannot look after ourselves.

Cheers

Hey now... I may be a Joker, but rooted in my nonsense was a bit of non-nonsense. I'm a lowly a mechanical guy, with a 2 year electrical degree (just enough to know that I don't know enough). I honestly didn't know what "CT" meant, I could have guessed all day, with no success, as the acronym "CT" could literally mean hundreds of things.

My point is any time you use an acronym, spell it out the first time it's used, then go ahead an use i the rest of the time, but I have seen so many posts that read something like:

"How to disable the KP on a DSS without knowing the JW, and please explain where IPC is applicable?"

I think you can all agree that that could mean anything or nothing at all. It's just a pet peeve of mine

Bye, bye.

i agree that many things may not be in the text books, but are surely available on the web, for example....

An extract from that website....

Where there is a will...there is Google

There is a ppt file here which gives quite a bit of information on CTs.

thanks a lot for encouraging me and replying to my posts. i have recently joined this forum ( probably in this august ) and do not know that questions are posted by students for their assignment soultions. but to clarify my status let me give you refrence of some of my posts :

1: i asked about the colors of indicating lights on HV,MV and LV switchgears . now have you seen any university having such switchgears and studenst asking about them ?

2: the firm where i am has switchgears from siemens, so i asked about the control drawings logic symbols of siemens drawings. i think no student will care about sysmbols used by siemens in their control drawings

3:i asked about reverse power setting of my 300 KVA genset and shared an experience of my friend from cummins engine (maximum 20% settings ). will any university student know about cummins engines and their settings ?

now if any one still has doubt , then he has the right not to read and not to reply to my post. if some one has any information about a forum where there are people asking basic question, then kindly tell me. i will switch over to that forum / website .

regards,

I apologize for the question and it 's been 20 years ago that I left school,

and I know how to use a current trafo (CT) but untill now, I don't know what the initials l, k, L and K stand for

Like P stands for Power, and I stands for intensity, m for mass, etc..

What is the meaning of l, k, L, K

Most regards.
