A device for reactive power compensation in a high voltage network having at least one phase conductor, includes a high voltage connection for each phase conductor, first and second core sections of a closed magnet circuit, a first high voltage winding enclosing the first core section, a second high voltage winding enclosing the second core section and being connected parallel to the first high voltage winding, at least one saturation switching branch being configured to saturate at least one core section has controllable power semiconductor switches, and a control unit controls the power semiconductor switches for each high voltage connection. In order to avoid leakage field losses, at least one high voltage winding has a central connection and is connected at its winding ends to the saturation switching branch. The central connection is connected to the high voltage connection.
