A stationary induction apparatus includes a core, a winding, a tank, a refrigerant, a radiator, and a unit cooler. The winding is wound around the core as a central axis. The tank contains the core and the winding. The refrigerant is filled into the tank. The radiator is mounted to the tank and includes a first heat exchange unit capable of naturally air-cooling the refrigerant that is naturally convecting while allowing the refrigerant to flow therethrough. The unit cooler is mounted to the tank and includes a pump to forcibly circulate the refrigerant, and a second heat exchange unit to forcibly air-cool the refrigerant that is being forcibly circulated while allowing the refrigerant to flow therethrough.
