primary voltage meaning in Chinese

初级电压
一次电压
原电压

This voltage must be in phase with the primary voltage
这一电压必须与原电压相同。
Rated primary voltage
额定一次电压
As an example , finite element analysis and optimization design are made to a voltage transformer of rating primary voltage 35kv , rating secondary voltage 100v , rating frequency 50hz
并以额定一次电压35kv ，额定二次电压100v ，额定频率50hz的电压互感器为例，进行了有限元分析计算和优化设计。
If one of the windings , the primary , is connected to an alternating voltage source , an alternating flux will be produced in the magnetic circuit whose amplitude depends on the primary voltage
如果给其中一个绕组（称为原绕组）施加交流电压，则它将在磁路中产生交变的磁通，磁通的大小取决于所加电压的大小。
The meter adopts digital synchronous sampling and micro technology to accurately measure true rms of transformer ' s primary voltage , current , power , power factor , true rms ( ac ) or average ( dc ) of secondary voltage and current , true rms of secondary voltage ripple
