首先要弄清楚一点:! e1 R* q- a2 y# I
LZ测的是高温绝缘电阻,这个应该是没有问题的。

C 3005-1993有如下规定:
$ m0 T8 `5 F* b- D# W9.2 Insulation resistance at high temperature: Sample a suitable length of a core specimen from the product, immerse it in water at a spesified temperature +-1 C, until the temperature of the insulation is stabilized, and then measure the insulation resistance by the method of 9.1. Do not carry out temperature conversion.$ @8 H1 u/ Y3 a9 s. t
这段话中,抽取的是CORE SPECIMEN,参考国标70C绝缘电阻测试方法,这指的应该是芯线。
# v$ T" G* \( Y) d5 L6 v9 I最好是翻阅日文版C 3005上面规定的很清楚。不过我不懂日文---
