Claims4
A grid influencing system for a power supply grid, the system comprising:
- a current-conducting grid influencing component including a unified power flow controller;
- a vacuum circuit breaker including a vacuum circuit breaker tube containing an at least partly integrated pre-arcing device for actively generating an arc between two contact surfaces;
- and
- an ignition electrode for igniting the arc along an arc current path;
- wherein the unified power flow controller comprises:
- a first transformer to tap energy off of the power supply grid;
- and
- a second transformer influencing an impedance of the power supply grid by altering a phase angle between a current of the power supply grid and a voltage of the power supply grid.
