Capacities of a winding of a low voltage of the transformer are on the same equations, as for the high voltage line. On the same equations losses of power and tension pay off. Power of a winding of a high voltage pays off on the equations
The deviation of tension of the following knot of a network is defined by subtraction from a deviation of tension of the previous knot of loss of tension of the element connecting knots – the high voltage line or the transformer. For the transformer E tension additive size due to change of a position of RBV or RPN is added to a deviation of tension.
