HV feed to farmstead ?

My turbine was one of the last the get accredited for the FIT scheme.
We have approximately 400 metres of HV (11,000 volt underground 3 x 95mm) cable from the turbine RMU to our RMU near our farmstead.
Would it be feasable to install a re-manufactured 11,000V - 415V transformer at the farmstead RMU and would the lead/lag be correct for us to put the 415V direct into the BusBar on the farm side of the grid supply meters - We are at the end of a 11,000v 3 phase line for both our input and output. ?

Don’t know but it comes out of our turbine at 690 v and then to substation tx 690 to 11000v. We have a supply from the 690 side down to the farm where there is another tx taking it to 415.

Iam no expert.
I assume that you have the turbine purely on an export meter at present and you would like to use the power from the turbine which currently is being exported to feed your farm.
I also assume the inverters are at the turbine and the feed is then stepped up to 11,000 volts and the export meter is sited near the farm stead
If this is so you will need your new sub station behind ie between the turbine and the export meter. Then scrap the old feed to the farm as you cannot have two feeds in which you effectively would have.
I am not sure about metering on the 11,000 volts, although I cannot see why it cannot be done as these larger meters work by clamping over the cable.
You really need to speak to an expert. It wont be cheap and it is a pity it was not done when the turbine went in
