The more modern if more elaborate partial-discharge measurement is better suited than such test meathods as it is almost entirely non-destructive.
這是Concept公司的產(chǎn)品SCALE315的Datssheet中關(guān)于耐壓的一段注釋,本人沒搞清楚,請(qǐng)朋友幫忙.
請(qǐng)朋友幫助看一段話,謝謝.

如果還有什么測試方法比這種方法更精細(xì)的話,那就是無法破壞的拉．
謝謝您的解答.不過本人愚鈍,還是不太理解.這里把原來的一段完整貼上,還請(qǐng)您幫著看看.
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.
