9411567 Kelley The Department of Electrical and Computer Engineering at North Carolina State University will purchase a Hewlett-Packard 3577B Network Analyzer and an Apple Quadra 950 Computer. The new equipment will support ongoing power quality and efficiency research funded by the Electric Power Research Center of North Carolina State University. Increasingly, the line-current and line-voltage distortion produced by nonlinear loads reduces power quality and creates unexpected high-frequency loss. One project the network analyzer will measure line impedance to find the impact of line-current distortion on line-voltage distortion. In a second project the network analyzer will measure transformer and motor impedance to find excess loss due to voltage and current distortion. The impedance measurements provide a better understanding of power system operation with nonlinear loads and are essential to maintain power quality and efficiency in the presence of current and voltage distortion. ***

北卡罗来纳州州立大学的电气和计算机工程系将购买一台惠普3577 B网络分析仪和一台苹果Quadra 950计算机。 新设备将支持由北卡罗来纳州州立大学电力研究中心资助的正在进行的电能质量和效率研究。 越来越多的非线性负载产生的线电流和线电压失真降低了电能质量，并造成意外的高频损耗。 一个项目是网络分析仪将测量线路阻抗，以发现线电流失真对线电压失真的影响。 在第二个项目中，网络分析仪将测量Transformer和电机阻抗，以发现由于电压和电流失真而导致的过多损耗。 阻抗测量提供了一个更好的了解电力系统的非线性负载的操作，是必不可少的，以保持电力质量和效率的电流和电压失真的存在。 ***
