根据电力研究院(EPRI)最近发布的研究报告,由于电力问题,包括电源波动和电压扰动,美国大型工业设施每年损失超过1000亿美元。家里的电灯闪烁不定会令人烦恼。而在工厂里,电力不稳定可能导致昂贵的设备发生故障,甚至过早报废。细微的电源质量事件常常越过传统保护网络而不被察觉,造成设备性能随着时间推移而降低。此外,许多电源质量扰动的来源是多个负载连接到同一网络,引起扰动穿越邻近设施和建筑物。为
According to a recent study released by the Electric Power Research Institute (EPRI), large-scale U.S. industrial facilities have lost more than $ 100 billion a year due to power problems, including power fluctuations and voltage disturbances. The twinkling of lights at home can be annoying. In the factory, instability can lead to expensive equipment failure, even premature retirement. Subtle power quality events often go unnoticed over traditional protection networks, causing device performance to degrade over time. In addition, many sources of power quality disturbances come from multiple loads connected to the same network, causing disturbances to pass through nearby facilities and buildings. for
