PURPOSE:To provide a voltage/current measuring system for distribution line in which the measuring work is simplified from the start of measurement to the preparation of a report while enhancing the accuracy in the measurement of voltage and current at a plurality of fixed points on a low voltage distribution line. CONSTITUTION:The system for measuring the voltage and current simultaneously at a plurality of points including a starting point A on a low voltage distribution line 3 immediately below a pole transformer 2 mounted on a pole 4 in order to step down a high voltage distribution line 1 comprises a voltage/current measuring unit 6a for master station disposed at the starting point A and voltage/current measuring units 6b, 6c for slave stations located at other points, wherein the master station and the slave stations are communicated through the low voltage distribution line 3. The master station measuring unit 6a transmits a command signal for simultaneous measurement to the slave station measuring units 6b, 6c which transmit measurement data back to the master station unit 6a. The master station unit 6a records data of all measuring units in a memory card and manages the data thus simplifying the measuring work.
