Abstract
A de-energized tap changer is disclosed that includes a contact rail assembly, a gear assembly, a handle assembly and a transmission system that compensates for angular misalignment of the gear assembly and handle assembly. The transmission system includes two elongated members with attached blocks that fit inside a hollow tube and when the handle of the de-energized tap changer is rotated, torque is transmitted through the transmission system to the gear assembly which drives the movable contacts.
