Magnetically controllable inductor coil in a series circuit

An apparatus for dynamic load flow control in a high-voltage network having a phase conductor and at least a first high-voltage connection for connection to the phase conductor, the apparatus comprising:

• a tank;
• first and second core sections being part of a closed magnetic circuit and being disposed in said tank;
• a first high-voltage winding surrounding said first core section;
• a second high-voltage winding surrounding said second core section, said second high-voltage winding connected in parallel with said first high-voltage winding;
• at least one saturation switching branch configured to saturate said core sections, said at least one saturation switching branch having controllable power semiconductor switches, said at least one saturation switching branch being disposed outside of said tank and mounted to be electrically insulated from ground potential;
• and
• a control unit for controlling said power semiconductor switches;
• said first and second high-voltage windings being connected to the first high-voltage connection and said first and second high-voltage windings configured to be connected to said at least one saturation switching branch;
• and
• a second high-voltage connection for connection to the phase conductor, said second high-voltage connection being connected directly, or through said at least one saturation switching branch, to at least one of said first and second high-voltage windings.
