Abstract

The invention relates to a method for adjusting a compensating inductor in a distribution network for electrical energy comprising an adjustable compensating inductor (K) between the star point of a transformer (M) connected to the network, such as a power transformer or a separate earthing transformer, and the earth, the inductance of the compensating inductor then forming a part of a total zero inductance (L) of the distribution network for electrical energy. The method comprises the steps, in which a total earth capacitance (C) of the network is determined by means of a zero voltage transient associated with a connection change or fault situation of the network, when the total zero inductance (L) of the network is known, a total zero inductance value (Lr) of the network is determined, the inductance forming a reactance whose absolute value is the same as the absolute value of the reactance formed by the total earth capacitance of the network at a nominal frequency (fn), and the compensating inductor inductance (Lk) is adjusted so that the total zero inductance of the network equals the value calculated above.
