Grid Energy Meter Error Research under the Influence Condition of Temperature
This paper selected the temperature as the influence quantity to discuss the variation characteristics of the grid energy meter’s key components, and the error change of the grid energy meter. It also built a complete grid energy meter simulation model by establishing the mathematical model of the key components. Laboratory tests showed that the absolute value of the meter error is based on reference temperature, which increases with the increase of temperature.
