Abstract: A method for operating a drive of a vacuum interrupter in opening mode includes: dividing an opening movement of at least one movable contact into serial phases, an opening phase, and an isolating phase, driven in at least two different velocities. In the opening phase a velocity of the opening movement is lower than in the isolating phase.

Abstract: An arc mitigation apparatus includes an arc mitigation device and a solar cell. The arc mitigation device is configured to be mounted to a low-, medium-, or high-voltage switchgear. The arc mitigation device is configured to stop or limit current flow within at least one part of the low-, medium-, or high-switchgear when activated. The solar-cell is configured to be located within a compartment of the low-, medium-, or high-voltage switchgear. The solar-cell is configured to cause the arc mitigation device to activate due to radiation from an electrical arc of the switchgear impinging upon the solar-cell.

Abstract: A three-position disconnector switch includes a platform, a power in contact, a power out contact, an earthing contact, and a piston. In a first position, the piston contacts the power out contact and the power in contact. In a second position, the piston contacts the power out contact. In a third position, the piston contacts the power out contact and the earthing contact. The piston moves along an axis to transition between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.
