Motor Protection vs. young engineer

Motor Protection vs. young engineer

Motor Protection vs. young engineer

(OP)
I have just started out in a very large company as a young engineer working on motor protection.  I found out (surprise) that I know very little about protection.  Now I am trying to find information on the net, but all that keeps popping up is product list, advertisment exc. I need hardcore theory. The Libs here in South Africa is not that brilliant, so what I'm asking is for someone to give me some pointers/struct tree of topics I can learn and find info on.  I mean it is just to steer me in the right direction.  Additional links would be excellent!

At this moment I am not doin a lot, just spreadsheet, documentation and info gathering and I dont blame anybody and therefor I need to educate myself more asap.  The elder Engineers are to buzy on this project and dont have time to stop and dump some knowledge on me.

Help me to help myself!

RE: Motor Protection vs. young engineer

thread238-163161 has some links to the best of the free resources, plus a reference to a further good book. A good book which is popular over here in the UK is "Protection of Industrial Power Systems" by T. Davies and published by Newnes / Butterworth-Heineman

RE: Motor Protection vs. young engineer

Another thing you can do is read a manual on a multifunction motor protection relay (Multilin SR469 for example) to learn what it can do.  This will let you know what you don't know, so that you will know what direction to focus your research and keywords to look up.

RE: Motor Protection vs. young engineer

The thread had links to specific chapters of the "Art and Science of Protective Relaying". You access  the whole thing here:

Thanks

If their is any more info you can direct me to, please let me know.  I made a valuable input today in one of our meetings after reading through the relay handbook last night I got from one of the above links.

Knowledge is a powerful tool, even in the hands of the incompetent.  

RE: Motor Protection vs. young engineer

You might also check into protection requirements set by your laws. I know of some locales that have voltage differntial and duration before trip limits that must be applied to new machinery...

RE: Motor Protection vs. young engineer

hi there, go to www.bussmann.com, great place, great devices. They have downloadable catalogs and technical explanatory manuals etc.
