Not really a confirmation, but in patent US6087738 Variable output three-phase transformer Robicon claims that the main benefit of their invention is to achieve more precise control of motor starting voltage, so in IMO this would be a viable solution to limit dc cap inrush current. Appears to...
Try:
Check that t012rin is in your matlab work directory (or path)
>> ! t012rin "test.t01"
>> ! "t012rin test.t01"
>> dos('t012rin test.t01')
Rewrite the batch file as a Matlab script
Good luck!
Interesting discussion, I think all posters have provided good explanations, Homer has possibly nailed it but I would nevertheless like to give my explanation. I have to use some equations but the explanation is IMO simple and it is a slightly different approach compared to previous posters...
I found this in the above LTSPICE forum, from "Rick". Apparently, pwl has a hidden file option:
A pwl (piece wise linear) file should work for this. Place a voltage or current source on the schematic. Then put the cursor over the source and the press Ctrl right click. Now in the value field...
Sorry, can't help you on that one but are you aware of http://tech.groups.yahoo.com/group/LTspice/ ? You need to register and you need a Yahoo account but it's a good forum.
Well, if you look at fig 12.5 in ftp://ftp.elteknik.chalmers.se/Publications/PhD/SalinasEnerPhD.pdf you'll see that they shielded a couple of transformers, no reactors though as fas as I can tell but I have honestly not really read it in detail. That, and some other actions, appeared to work...
I would respectfully say that mr waruss is right, the screen is due to induced eddy currents. Please see fig 6 in this paper http://www.emc.york.ac.uk/cost261/Lille%20proceedings/Enerpaper.pdf .
To my knowledge, this technique is occasionally applied to screen substations installed in or near...
144x: Are you referring to a grounded single star bank or an ungrounded double star (wye) bank. If it is a single bank, then I agree with elektroeng but in case of a double bank the CT may actually be able to detect unbalance. However, there may be other unbalance protection relay installed that...
