小电流智能电能表需量示值误差测试技术研究

Study on Test Technology of Low Current Intelligent Watt-hour Meter Demand Indication Error

需量测量功能是智能电能表计量的1项重要技术指标,需量示值误差试验是电能表检定中的1项重要内容。文中主要对额定电流在1A以下的智能电能表在需量示值误差测试中出现的问题进行分析,以试验数据为切入点,研究小电流规格的智能电能表的需量示值误差测试技术,并提出了解决办法及改进建议。

Demand measurement function is an important technical index of intelligent watt-hour meter. Demand indicalinn error test is an important content in the calibration of watt-hour meter. In the light of intelligent walt-hour meter with rated current under IA, the problems exited in demand indication error test are analyzed. Started from test data, the test technology of low current intelligent wall-hour meter demand indication error is studied, and related resolution and suggestion are put forward.
