PROBLEM TO BE SOLVED: To save received power by raising an input voltage to a power load in a range not hindering the power load and by suppressing the generation of reactive power and unnecessary power, in a power wiring circuit which includes a high-voltage transformer for power reception and the power load. SOLUTION: The wiring circuit supplies a power load circuit with a secondary voltage that is obtained by conversion with a three-phase high-voltage transformer. In this power-saving wiring circuit, (a) a three-phase high-voltage transformer receives electricity at its primary terminal with a voltage value higher than the voltage value of its primary terminal that is used usually, and outputs a secondary voltage lower than its usual voltage value to its secondary terminal, and (b) a low-loss transformer raises the secondary voltage to a rated voltage value of the power load or over and supplies it to a power load circuit, and (c) this circuit generally suppresses reactive power and unnecessary power that are generated in a wiring circuit including the three-phase high-voltage transformer and the power load circuit.
