PURPOSE: A power management system using wire and wireless communication is provided to monitor an electric leakage, a fault, and a fire of a power device in real time by communicating with a distribution unit by wire/wireless. CONSTITUTION: A distribution unit(30) distributes power of a low voltage to a power device that is a kind of an electric installation system. The distribution unit senses the status of transformers and various power devices, transmits and receives the sensed result, and switches the power. A power management device(70) checks the status of the transformer, the distribution unit, and the power device by communicating with the distribution unit by wire/wireless and takes the statistics on the checked result according to the period. The power management device controls the on and off of the power and switches the distribution unit according to the statistic result. |
