Abstract

The invention concerns a method for elimination of disturbances in an energy transmission network. The energy transmission network comprises a main transformer 2 with a star point 12, phase conductors L1, L2, L3 and a null conductor N, which at one end 3 is connected to the ground potential and the star point 12 of the transformer 2 and at its other end 4 to the loads 5, in which energy transmission network the electric power is transmitted at a frequency f. According to the invention, a band blocking filter 1, 1', 1" with a centre frequency of 3*f is connected in between the star point 12 of the transformer 2 of the connection points 4, 4' of the loads 5, 5'. <IMAGE>
