Research ArticleOpen accessIn the author namesRepower and Evaluation of New Power of Synchronous GeneratorsS.P.Y. Santos, E. Delbone, E.F. Carvalho, L.N. MartinsProblem Statement: Useful life of winding isolation is about 30 years. It can be reduced when it is submitted to overloads or when it is worked in aggressive environments. Approach: When retrofit is done, an increasing to superior isolation class is recommendable. So, generator capacity can be increased and pay back could be excellent justifying the investment. Result: Several Brazilian’s … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,800 accessesView PDFCite
Research ArticleOpen accessIn the author namesSynchronous Generator Disturbance Provoked by Induction Motor StartingS. P.Y. Santos, E. Delbone, E. F. Carvalho, L. N. MartinsProblem statement: This study presented an alternative procedure for the starting of large Inductions Motors (IM) in isolated generation systems. Approach: In isolated generation systems on stand-by or base load, the starting of the IM provoked sags frequently beyond the ability of the other consumers in the plant to stand. Manufacturers' solutions always recommend a supersized generator to decrease transient … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 6,939 accessesView PDFCite
