The present invention provides an electric meter equipped with a black box. According to the present invention, the electric meter equipped with a black box can monitor a power state with only a simple configuration in which an electric meter installed in an ordinary house, an office, a factory, or an industrial facility is integrated with a power black box which detects, stores, and outputs power state information including a voltage, a current, a frequency, temperature, and a peak voltage, and can accordingly reduce costs for building a power state monitoring facility and eliminate constraints on installation environments as well. According to the present invention, the electric meter comprises: a power measurement unit measuring power consumption in one set area among a general house, an office, a factory, and an industrial facility; a power black box unit detecting, storing, and outputting the power state information, including the voltage, current, frequency, and power line temperature of power flowing through a power line connected to the power measurement unit, while monitoring the information; and a meter case in which the power measurement unit and the power black box unit are installed. The power black box unit comprises: a power state information detecting module detecting the power state information; a power state information storage module receiving and storing the power state information from the power state information detecting module; and a power state information output module outputting the power state information to the outside by receiving the information from a selected module among the power state information detecting module and the power state information storage module. |
