ELECTRIC POWER MEASUREMENT SYSTEM

PROBLEM TO BE SOLVED: To provide an electric power measurement system that is easy to install and with which it is possible to lighten a visiting work load.SOLUTION: The electric power measurement system comprises: a measurement device 2 which is disposed on an electric pole 101, has a plurality of drop wires 102 connected to each user home H being connected to a power supply-side low-voltage wires 103, detects electric power flowing to the user home H side via the drop wires 102, and calculates the supplied amount of electric power flowing to each user home H; and a charge server 3 for calculating an electric power charge on the basis of the supplied amount of electric power received from the measurement device 2 and communicatably connected to the measurement device 2. In the charge server 3 there is provided a used amount calculation task 33 that calculates the amount of electric power consumed during an interval from the measurement device 2 to the user home H on the basis of the resistance value of the drop wires 102 from the measurement device 2 to the user home H, and subtracts the calculated amount of electric power from the supplied amount of electric power.SELECTED DRAWING: Figure 1 【課題】 設置が容易で、かつ、訪問作業量を軽減することが可能な電力計量システムを提供する。【解決手段】 電柱１０１に配設され、各需要家宅Ｈに接続された複数の引込線１０２と電源側の低圧線１０３とが接続され、引込線１０２を介して需要家宅Ｈ側に流れる電力を検出して、各需要家宅Ｈに流れる供給電力量を演算する計量装置２と、計量装置２と通信自在に接続され、計量装置２から受信した供給電力量に基づいて電力料金を演算する料金サーバ３と、を備え、料金サーバ３に、計量装置２から需要家宅Ｈまでの引込線１０２の抵抗値に基づいて、該計量装置２から該需要家宅Ｈまでの間で消費される電力量を算出し、該電力量を供給電力量から減算する使用量算出タスク３３を備える。【選択図】 図１
