Devices called synchrophasors can sample voltage and current 30 times a second or faster-giving utilities and system operators a far more accurate view of the health of the grid.
而被称为“同步向量”的设备能以一秒30次或更快的速度采样电压和电流——向电力公司和系统操作员提供有关电网健康状况的信息更为精确。
The system includes a Model 6220 Current Source to supply the current through the sample and a Model 2182A Nanovoltmeter to measure the resulting voltage drop.
该系统包括用来提供流过样品的电流的6220型电流源和用来测量产生的电压降的2182A型纳伏表。
The tester with DSP core could get excellent results by judging and adopting the different value of voltage and current, programmed amplifying and changing the frequency of sample.
系统以DSP为控制核心，可自动识别并适应不同的电压和电流等级，采用程控放大、变化采样频率以获得优化的阵列测试效果。
