Circuit connection as shown in a, b, in which a star-shaped FIG winding shunt capacitance of the connection, Fig. B triangular winding capacitance in parallel connection. FIG W
orking capacitance cc capacity is calculated by the following formula: C 19501Ucos µ. Where C is the capacitance of the work ( F); I is the rated current (A); U single-phase rated voltage (v); cos µ into work rate factor.
