  1. Hello I have just come across your article which dates from about ten years ago and which is very interesting.
    Not being an electricity enthusiast, there is a calculation that I did not understand. (V3.UI = V3.400.2.8 = 1938VA). If you could explain it to me more clearly if he did not is not too late, because I would like to make myself a small all-electric generator and; plans for your first wind turbine if you don't mind.
    Thank you in advance.

    1. Hello Michel, almost 2 years late.

      This is the formula for calculating the apparent power, which is used to size the power of electrical equipment, the unit of which is the Volt Ampere (VA).

      The formula is S = V3 x U x I

      By V3 we must understand "root of 3" since we are talking about three-phase therefore 1,732
      With a voltage U = 400 and an intensity I = 2,8

      1,732 * 400 * 2,8 = 1939 VA

      1. Hello, I am contemplating your very interesting work, but I come up against one of your calculations for the values ​​of capacitors.
        Indeed reactive power = root of 1939 X 1938 - 1454 X1454 = 1231 VAR?
        indeed by following the mathematical priorities: (√1938 X 1938) - (1454 X 1454) we are very far from your result, can you deepen, hoping that you will receive my message.
        good to you guys
