PROBLEM TO BE SOLVED: To provide a power measurement device in which a power consumption value can be calculated even at a timing of communication.SOLUTION: A power measurement device includes: first and second power operation parts 3 and 4 each for calculating a power consumption value of an electric device at a predetermined cycle, and interrupting calculation processing of the power consumption value so as to perform communication; and a control device 5. The control device 5 sequentially transmits, at a cycle, a request signal for causing each of the first and second power calculation parts 3 and 4 to transmit the consumption power value. The control device 5 receives the power consumption value sequentially transmitted from each of the first and second electric power calculation parts 3 and 4 in accordance with the request signal, to thereby obtain the power consumption value for each cycle of an electric device. |
