Classification: CPC G | IPC G

Claim 1:
2. The power measurement device according to claim 1, wherein
the first average value calculator calculates the average value of the active power corresponding to the frequency of the three-phase alternating current power by selecting a prescribed number of active power average values among the plurality of active power average values at frequencies near the frequency represented by the frequency information, and by performing linear interpolation of the selected prescribed number of active power average values, and
the second average value calculator calculates the average value of the reactive power corresponding to the frequency of the three-phase alternating current power by selecting a prescribed number of reactive power average values among the plurality of reactive power average values at frequencies near the frequency represented by the frequency information, and by performing linear interpolation of the selected prescribed number of reactive power average values.
