Abstract

A power consumption measurement apparatus includes a power meter, a multi-meter, and a data collector. The power meter obtains first power consumption data indicative of the power supplied from an AC power supply to an AC-to-DC converter. The multi-meter obtains second power consumption data indicative of the power consumed by each of loads. The data collector synchronously collects the first power consumption data from the power meter and the second power consumption data from the multi-meter. A method for measuring power consumption is also provided.
