摘要
本文结合我国目前电力系统无功功率、电压和电流测量及其现场检验的现状,探讨了采用霍尔电流传感器、数字式仪表和精密钳型电流互感器等,提高电力系统无功功率、电压和大电力用户电流测量及其现场检验准确度的新方法。
Based on the current power system used in China including reactive power, voltage and current measure- ment and on - site inspection, a new method to improve the reactive power, voltage and current measurements of large elec- tricity users and accuracy of site inspection by applying the Holzer current sensor, digital instrument and precise pincer type current transformer is discussed.
