Method for quickly calibrating error of three-phase intelligent electric energy meter

The invention discloses a method for quickly calibrating the error of a three-phase intelligent electric energy meter. The method comprises the following steps of: applying rated voltage and rated current to a tested electric energy meter so as to make the electric energy meter enter a meter calibrating state; transmitting an instruction by using an upper computer, and reading an actual voltage value and an actual current value of the electric energy meter; setting a calibrating power factor as 1.0, and computing an error value according to standard power of a meter calibrating table and actual power of the electric energy meter; inputting the error value into the tested electric energy meter; setting a phase segmenting factor; computing an interval error value between actual power of each interval and the standard power of the meter calibrating table; and finishing the meter calibrating process. The method for quickly calibrating the error of the three-phase intelligent electric energy meter has the advantages of high efficiency, capability of ensuring product yield and capability of calibrating the meter reliably, safely and quickly.
