摘要：A power measuring apparatus (112) is provided with: a line connector (112s)

connected to a power source line (11), which supplies power to equipment; and ameasuring circuit (1122), which measures a voltage and a current supplied to theequipment by means of the connected power source line (11). The power measuringapparatus (112) is also provided with: a calculator (1129) which calculates, on the basis ofthe measured voltage and current, power consumed by the equipment; and a

transmission line connector (Pt) connected to a transmission line (21) that transmits dataused for the purpose of monitoring the equipment. Furthermore, the power measuringapparatus (112) is also provided with a transmitter (1126) that transmits data indicatingthe calculated power to the transmission line (21). Consequently, the power measuringapparatus can be installed in equipment at lower cost than before.
