FIELD: electricity.
SUBSTANCE: invention relates to an arrangement (1) for controlling at least one load (D1, D2, D3). In order to provide auxiliary power source extraction tool from the power source in order to control shunt switching, arrangement (1) circuit contains the input terminal (11) to connect to the power supply source (30), output terminal (12) to connect to at least one load element (20, 21, 22, 23), control circuit (10) containing control device (13) that is adapted to control at least one load element (20, 21, 22, 23), and device (C) of energy accumulation which is adapted to supply power to control device (13). In addition, a controlled bypass switch (M4) is provided. The said bypass switch (M4) and said control circuit (10) are connected in parallel and connected between said input terminal (11) and said output terminal (12). The circuit arrangement (1) is adapted to operate the bypass switch (M4) for controlling the power provided to the control circuit.
EFFECT: reduction of plant losses.
