请教：“virtual impedance”和“conventional impedance”的翻

IEC60335-1 14.1 Ed4.1和Ed4.2同一段分别为：

The impulse test voltage has a no-load waveshape corresponding to the 1,2/50 μs standard
impulse specified in IEC 61180-1. It is supplied from a generator having a virtual impedance
of 12 Ω. The impulse test voltage is applied three times for each polarity with intervals of at
least 1 s.

The impulse test voltage has a no-load waveshape corresponding to the 1,2/50 μs standard
impulse specified in IEC 61180-1. It is supplied from a generator having a conventional
impedance not exceeding 42 Ω. The impulse test voltage is applied three times for each
polarity with intervals of at least 1 s.


请问其中：“virtual impedance”和“conventional impedance”的翻译和定义

virtual impedance 有效阻抗
conventional impedance 虚拟阻抗
不知道对不对！
我在IEC60335-1 14章中没有前面一段话，只有后面的一段话。

对该试验，我认为是一样的，前一段是IEC里说的有效阻抗12欧，后一段是EN里说的标准阻抗小于42欧，一个定量，一个半定量说法。
