摘要
本文介绍了一种便携式低压电网数据采样与分析系统。该系统由信号变换电路、数据采样卡和工控机组成,能实现电网三相电压、电流数据的精确采样,并且可以分析电网的谐波、三相不平衡度和功率因数。
A portable sampling and analyzing system of low voltage power system is introdueed in this paper. This system is made of signal transform circuit, data acquisition card and industry control computer. This system can be used to sampk; precisely three-phase vollage and current. It also have the function of analyzing the harmonics, the three-phase imbalance degree and the power factor.
