Then, we turned the watermill on to test it when loaded, and it worked.
From then, we could think about the wiring.
The theoritical power of a mill is calculated by multiplying the flow of the millcourse (in litres per second) by the height of water (in metres) and by dividing by 75.
The turbine of our watermill turns at 200 rounds per minute when it is ticking over and the generator turns at 1500 rounds per minute when on charge.
At this stage of the installation, we called on a former hydraulic engineer who recommended us a gearing down by a more supple and quieter belt instead of gears.
