In order to further study the metering performance of meter and ensure the accuracy and reliability of running Watt-hour meters under multi-dimension working conditions, this paper makes a series theoretical and experimental study of it and proposes an evaluation method, and with it we can get the measurement performance of meters working in multi-dimension disturbances field conditions. Application results show that we can use this model to precisely evaluate the measurement performance of meter under multi-dimension environment disturbance, find questions of meters in working condition timely, and ensure the accuracy and reliability of running meters in field conditions.
