The more modern if more elaborate partial-discharge measurement is better suited than such test meathods as it is almost entirely non-destructive.
这是Concept公司的产品SCALE315的Datssheet中关于耐压的一段注释,本人没搞清楚,请朋友帮忙.
请朋友帮助看一段话,谢谢.

如果还有什么测试方法比这种方法更精细的话,那就是无法破坏的拉．
谢谢您的解答.不过本人愚钝,还是不太理解.这里把原来的一段完整贴上,还请您帮着看看.
The test voltage of 4000 Vac(rms)/50Hz may be applied only once during one minute. It should be noted that with this (strictly speaking obsolete) test methord, some (minor) damage occurs to the isolation layers due to the partial discharge. Consequently, this test is not performed at CONCEPT as a series test. In the case of repeated isolation tests (e.g. module test, equipment test, system test) the subsequcent tests should be performed with a lower test voltage: the test voltage is reduced by 400V for each additional test.
