【摘要】 传统方法设计的电网功率因数计量仪器已不适应干扰谐波日益严重的电网环境。利用ADE7763电能计量芯片测量有功电能和视在电能的功能,成功地设计研制了适应干扰环境的功率因数计量仪器,仪器结构简单、性能稳定、达到了设计精度要求。更多还原

【Abstract】 The power factor instrument designed in the conventional way is no longer adapti ve to the electric network environment which is interfered hardly with harmonic .Taking advantage of the function of measuring active energy and apparent energy of the energy measurement IC, a kind of power factor instrument we have been successfully designed, which is well adaptive to the disturbed environment. The instrument has the character of simple structure and stable performance, and it can satisfy the requirement of high precision.更多还原
