My wife and I run a chambres d’hotes from our property which is in a remote area in the south west of France. We have a 3 phase electricity supply which is spit at the consumer unit for different cicuits. I have converted our barn for additional bedrooms and summer kitchen and have run a cable (about 40m of 2core 10mm sq) from one of the phases and neutral in the consumer unit to the barn for its power requirements. However, the voltage at the barn end is less than 200v (at the consumer unit it is only about 220v) and I find that when the water heater in the barn cuts in there is a power dip and the lights dim.
My question is this. Would a practical solution to the problem be to install a 3 phase transformer in the barn and run all 3 phase to it and then take off different circuits for the power and lighting circuits? If the answer is yes what winding configuration on the transformer would be best (i.e. Y or Delta)? Are there any configurations that would not be allowed? Also, would EDF have any objections to what I propose?
