Abstract
A power supply arrangement, especially in connection with a conductor ( ) of a medium-voltage overhead line, which arrangement comprises a power supply ( ) and a first and second element ( ) made of an electrically conductive material, which are connected electrically to the power supply for feeding energy to the power supply. The first element ( ) of the power supply arrangement is arranged to be close to the conductor ( ) and has a capacitance (Ce) to an element in a second potential, the capacitance being arranged to charge itself by effect of an electric field generated by the voltage of the medium-voltage conductor, and said second element ( ) is arranged to have a galvanic or capacitive connection with the conductor ( ) for feeding energy to the power supply ( ) from the potential difference between said first and second elements.
