Embodiment 1
[0026] The invention of this example provides a load record test method for electric energy meters, which includes summarizing the load record test into four steps by changing the load record mode word, the load record interval time, and optimizing the combination of integrated test items.
[0027] The most recent load record block of the first test: "voltage, current, frequency", "active and reactive power", "power factor", "active and reactive total energy", "I and II quadrant total reactive energy", " "Current demand" and can be set within the range of 1 to 60 minutes. The interval time of each type of load record can be the same or different; the second test is the latest load record block: "voltage, current, frequency", "active, reactive Power", "power factor", "active and reactive total electric energy", "ⅢⅣquadrant reactive total electric energy", "current demand" and can be set within the range of 1 to 60min, the interval time of each type of load recording can be The ...
