PROBLEM TO BE SOLVED: To provide an inverter-device saved-power measuring/displaying device for measuring and displaying the amount of saved power by an inverter device provided between an alternating-current power supply and a load. SOLUTION: This device is equipped with a memory part 20D for memorizing initial data expressing a relation between the output percentage and the power of an inverter device 10 provided between an alternating-current power supply 11 and a load 12, a three-phase power computing part 20A for detecting alternating-current power flowing from the alternating-current power supply 11 into the inverter device 10, a computing part 20B for acquiring data expressing the output percentage from the inverter device 10 and computing the amount of saved power by the inverter device 10 based on the output percentage and the power of the inverter device 10 at the time of data acquisition, and on the initial data memorized in the memory part 20D, and a display part 20E for displaying the amount of saved power that is computed by the computing part 20B. |
