Abstract
A control device includes an information acquisition unit configured to acquire information related to an air density in a coil and information related to a voltage applied to a rotary electric machine, an insulation determination unit configured to determine whether or not dielectric breakdown occurs in the coil based on the information related to the air density and the information related to the voltage acquired by the information acquisition unit, and configured to determine whether or not an insulation state of the coil is needed to be maintained by supplying an oil to the coil, and a drive instruction unit configured to drive an oil supply unit, when the insulation determination unit determines that dielectric breakdown occurs in the coil and determines that the insulation state of the coil is needed to be maintained by supplying the oil to the coil.
