<P>PROBLEM TO BE SOLVED: To simplify a structure of an electric power measuring device and an electric power measuring system. <P>SOLUTION: In an electric power measuring device 10A, coils L1 and L2 which insulate an electric power system 101 and a network cable 50 are used for communication with a display device 20. Thereby, a network between the display device 20 and the electric power measuring device 10A is not required to be provided separately. Thus, the structure of an electric power measuring system 1 can be simplified. The display device 20 and the electric power measuring device 10A are only electrically connected with a coil L3 and the coil L1, so that the display device 20 can be easily attached to or detached from the electric power measuring device 10A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
