Zusammenfassung:	PURPOSE: An intelligent AMI transformer management system is provided to maximize the efficiency and maintenance of a system. CONSTITUTION: A transformer is connected to a current meter of a wireless neutral line and transforms high voltage into low voltage. A watthour meter(200) displays watt-hour used in houses. A data collecting unit(300) reads the value of the watthour meter through a PLC modem installed in the watthour meter using PLC communication. A current meter measures the current flowing in the neutral line with the data collecting unit and wirelessly transmits the value of the current. A CDMA communication device(400) periodically transmits data from the data collecting unit to the upper end. A server(700) determines the overload of the transformer.
