ABSTRACT:
A coaxially aligned transformer having a secondary coil wrapped with a high dielectric insulating material wrapped on a support member and slidably supported between a lock block and a support base to permit the transformer electrical parameters to be adjusted by sliding the transformer core. A primary coil is supported coaxially about the secondary coil. Both the primary and the secondary coil include voltage divider segments having equal inductance with the primary coil segments arranged in phase and the secondary coil segments arranged 180.degree. out of phase. The secondary coil is completely insulated and isolated from ground. The primary coil has a number of taps which are connected to the contacts of a multi-position switch so that the voltage in one of the segments of the primary coil may be varied so that the output of the transformer may be varied. This transformer provides a switchable primary circuit and a fully insulated secondary circuit.
