Four Power supply in a Plot..

Hi, I am facing one problem during my project...
We have one plot (110mx90m), which is divided into 4 sheds, each shed is getting supply from different transformer, so we have total four main distribution boards in a plot. Now local authorities in UAE for electricity is asking for change this whole power distribution system because it is dangerous for human being.. and asked us to make one transformer room for a 11kV/415v transformer. then from outgoing 415v should be in a main distribution board then each shed gets power supply though outgoing cable from main distribution board..
I just want to know kindly guide me what is a technically problem if we have four different cables feeding from four different transformers to four different sheds which have four different main distribution boards in each shed.

Hi Ali (or should it be Asad - I'm sorry I do not know the custom for the order of your names),
I am not sure what exactly you are asking nor am I an expert in power distribution. So my comments are purely for guidance and I am not an expert to give advice to you. Hopefully someone with Electrical distribution experience will answer your question.

As I see it, the power company wish to power your units from a single transformer, posibly from different phases, although this is not clear. This may be due to their provision of a higher voltage grid (the 11kV feed) or because of issues with your existing transformers. This information should be given by them. Given the size of your plot, but not knowing your total power consumption (in kVA), I am assuming that it is not huge in which case this change makes engineering sense.

You should ask the power company for an explanation of what they are doing and why.

Hope this helps you.

I asked from power company actually this plot got old connections some 10 years back and every thing is working fine i dont know why company want a single transformer on the name of human being safty and total load in all sheds are 450KW.
