摘要
介绍一种完整意义的工频相位标准源,即不仅可输出电压对电流的标准相位角,还可以输出电压对电压、电流对电流的标准相位角,其相位精度可达0.02°。
This pager introduce a better commercial frequency phase standard source.Not only can it exports the phase of voltage to current,but also the phase of voltage to volt-age and the phase of current to current.Its accuracy is0.02°.
