Abstract
A current interruption system may include an electromechanical switch coupling an electrical source and an electrical load along an electrical line of a power delivery system. The current interruption system may also include a controller that may receive an indication of an electrical characteristic along the electrical line, determine a fault condition based on the electrical characteristic, and transmit instructions to interrupt a first current through the electromechanical switch according to a first mode or second mode based on the electrical characteristic and the determination of the fault condition. Additionally, the current interruption system may include a voltage source converter (VSC) that may receive the instructions from the controller, interrupt the first current according to the first mode or the second mode, and reduce a second current through the VSC to zero.
