摘要
采用一种新的简明的方法推导了压力波法 (PWP)的测量原理 ,并对压力波法和电声脉冲法 (PEA)作了比较 ,得出这两种测量方法在物理本质上的相通之处 ,并且采用本实验室自行研制的piezo PWP PEA联合测试系统对交联聚乙烯样品中的空间电荷进行测量 。
In this paper, a new illation of the principle of PWP (Pressure Wave Propagation) method is presented, and the results, after comparing the PWP method with the PEA (Pulsed Electro-Acoustic) method, indicate that the two methods very resemble with each other in physics. In order to testify the conclusion, the measurement of space charge distribution in XLPE by using the combined system of piezo-PWP/PEA has been corried out, and the experimental results confirm the conclusion.
