摘　　要：霍尔效应是1879年美国物理学家霍尔读研究生期间在做研究载流子导体在磁场中受力作用实验时发现的。阐述了霍尔效应的原理，霍尔元件的特点和分类以及在各个领域中的应用。在电力测量中，用普通的电压、电流线圈构成的功率表测量精度低、反应速度慢，不能满足精度要求。为了提高无功功率的测量精度，本文将霍尔传感器引入无功功率的测量中，介绍了霍尔效应、霍尔传感器工作原理、无功功率理论及霍尔式功率表的制作原理，为电力无功功率的快速、精确测量提供了理论依据。Hall effect is found in the 1879 U.S.physicist,Hall graduate student to do research carrier conductor in a magnetic field by the force experiments.On Hall effect principles,characteristics and classification of the Hall element,as well as applications in various fields.Power measurement,with a common voltage,current coil constitute the power meter measurement accuracy islow, the reaction is slow, can not meet the accuracy requirements.Order to improve the measurement accuracy of the reactive power, Hall sensors into the measurement of reactive power, Hall effect, Hall sensor working principle,the reactive power theory and the Hall of power production principle,for the power fast,accurate measurements of the reactive power provides a theoretical basis.
