The invention relates to an electric energy quality measuring device based on bluetooth, and aims at solving problems of reducing disordered field lines and reducing investment cost. The device comprises an acquisition module which is used for acquiring electric energy quality signals of monitoring points in a power grid and transmitting the electric energy quality signals to a bluetooth transmission module; and the bluetooth transmission module which is connected with the acquisition module and used for wirelessly transmitting the electric energy quality signals to a mobile terminal, wherein the mobile terminal is used for analyzing electric energy quality of the monitoring points according to the electric energy quality signals. The bluetooth transmission module is adopted to transmit the electric energy quality signals. The constraint of a conventional wired circuit is eliminated by a short-distance wireless transmission communication technology so that the disordered field lines can be avoided. Meanwhile, the mobile terminal is adopted to analyze data. Compared with a large monitoring and analysis platform in the prior art, the electric energy quality measuring device based on bluetooth has advantages of being great in portability and low in cost.
