Hi Tanuj!
Reviewing the standard IEEE C37.99-1990 "IEEE Guide for the Protection of shunt Capacitor Banks" I dont found nothing about it.
I recommend Ask to manufacturer!
Good Luck!!
Hola OhioAviator!
The solution to your problem is a 51G relay with residual connection (the three ct's are connected in shunt with the relay)
I recommend read the IEEE C37.91-1985 for more info.
Good luck!!
Hi Gene!
I have some question: How many generators are connected?
There are feeding the same bus?
I said this because, when one generator (connected in parallel with others generators)loose (for any reason) the excitation current; the terminal voltage do not fall to zero immediatly, Why...
Sometimes a engineer have to resolve problems taking acount the enables materials in his warehouse, 125_KVA it too large power for that load but if you need resolve that problem with urgency and that transformer (125_KVA) it enable for install i said GO!.
Good Luck!
Its true jbartos, 5p10 CTs are governed by standard
IEC 60044-1, i was confused.
An excelent papers about this are in:
http://www.ieconsult.fr/ect195.pdf
http://www.ieconsult.fr/ect194.pdf
Best regards.
For more information you can read:
- IEEE Std C57.13 (IEEE Standard Requirements for instrument Transformers)
- IEEE Std 242 (IEEE Recomended practice for protection and coordination of industrial and comercial power systems)
Good luck!
I suggest you that forget your book for a couples of weeks and try first wiht one tutorial for matlab for learn in first place the basics things for understand the books examples.
If you dont learn some commands, procedures, etc, those codes will be chinese for you.
Good Luck!
