3 MVA-Distribution

11/21/2010 5:57 AM

Dear Freinds,

hope you would get time and energy to check on my question and ofcourse i would truly appreciate your helpful answers

at plant they decided to move from 2* 1.5 MVA Transformers (connected with bus coupler)to 3 MVA ..and yes there is dramatic load extension..

load in general would be CNC Machines ,compressor ,ACs and lighting

I hope you can help with some details regarding the distribution ,configuration and ratings of CBs and relays and cables(single core /3 core..)

perhaps , single line diagram of something close would be perfect

thank you inadvance

waiting your answers..
