本文件提供了一种高效、可靠的程序来测试内部电场 用于高压应用的绝缘材料，使用压力波传播 （PWP）方法。它适用于具有均匀绝缘材料和导电性的样品 磁场高于1 kV/mm，但也取决于样品的厚度和 压力波发生器。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document provides an efficient and reliable procedure to test the internal electric field in the insulating materials used for high-voltage applications, using the pressure wave propagation (PWP) method. It is suitable for a sample with homogeneous insulating materials and an electric field higher than 1 kV/mm, but it is also dependent on the thickness of the sample and the pressure wave generator.All current amendments available at time of purchase are included with the purchase of this document.
