Abstract
A controllable primary switch for isolating a transformer from a power grid or network. The controllable primary switch is mountable within and integral to the transformer and is electrically connected to high voltage feeder cables to allow the transformer to be disconnected from the power grid or network. The controllable primary switch includes one or more vacuum interrupters having first and second electrical switch contacts mounted inside the casing, an actuator for moving the second switch contact relative to the first switch contact in each of the one or more vacuum interrupters, and a handle connected to the actuator. The handle engages the actuator to move the second switch contact relative to the first switch contact.
