POWER STRIP AND POWER MEASUREMENT METHOD |
摘要 |
[Problem] To calculate power consumption with high accuracy at a jack portion in a power strip and a power measurement method. [Solving Means] A power strip includes: jack portions 1a; current meters 30 each configured to measure a current being supplied from the corresponding jack portion 1a to one of external electrical devices 71 to 74, and to output a measurement signal V s corresponding to a magnitude of the current; and a computing unit 33 configured to obtain instantaneous values I(t) of the current at a plurality of time points t on the basis of the measurement signal V s , and to calculate a power value using the instantaneous values I(t). The computing unit 33 configured to obtain the instantaneous values I(t) of the current by using any one of a first zero point V 01 and a second zero point V 02 as a reference. |
