Abstract
A power device, which includes: an energizing conductor; a power generation unit configured to generate power that is induced by a magnetic flux of a current flowing through the energizing conductor; a power device unit configured to use the power generated in the power generation unit as a power source; a short-circuit switch capable of short-circuiting an output from the power generation unit; and a sealed container in which the energizing conductor, the power generation unit and the power device unit are included, and an insulating fluid is enclosed in the sealed container. This power device is provided as a highly reliable power device, which is used in an AC power system and does not induce an excessive voltage in the power generation unit when the power device unit is stopped in the state where the energized state of the energizing conductor is maintained.
