Abstract: A high voltage electrical device includes a removable transformer module and a receptacle attached to the high voltage electrical device for receiving the removable transformer module. The removable transformer module is configured to mate with the receptacle as the removable transformer module is plugged into the receptacle in order to connect the removable transformer module to the high voltage electrical device. The removable transformer module includes a transformer for transforming a primary input voltage into a secondary output having a voltage greater than the primary input. The removable transformer module also includes secondary contacts for connecting the secondary high voltage output of the transformer module to the high voltage electrical device when the removable transformer module is plugged into the receptacle.
