I wonder about some comments in IEC 664-1:1992

2002-08-30 Thread Michael Jang

Dear members

I don't have a standard (IEC 664-1:1992).
But, I wonder about some comments in IEC 664-1:1992 as below;

1. What does mean R.I.V. (Rated Insulation Voltage)?
Is it working voltage or EUT's rated voltage?
If it is not... hm please explain for me.   ^_^;

2. Are Table 2's distances Basic requirement?
I don't have a standard, but anyone tells as talk.

3. If I will conduct IMPULSE TEST...
Must I apply between where and where?
(EUT has a Linear Transformer, SMPSs and communication boards)

I don't know so many things in standards.
Please give your help.

Michael Jang
