基准电源 meaning in Chinese

reference power supply

After the host computer sends the broadcast command to order measurement operation , all slave devices will start to sample the input signals synchronously . when the sampling operation has finished , devices installed on the capacitive equipments will calculate the phase angle difference ( oi ) between leakage current and the reference voltage signal , and devices installed on pt will calculate the phase angle difference between secondary voltage and the reference voltage signal ( ou )
我们把一个50hz的交流基准电源引到每台下位机内，主机发布一个广播命令要求pt和电容型设备上的监测装置同时采样，电容型监测装置计算出泄漏电流和基准源之间的相位差_ ( oi ) ， pt上的装置计算出二次电压与基准源之间的相位差_ ( ou ) 。
