Hello,
According to the IEEE std 802.3-2002 section two, the electrical separation shall withstand the following electrical strengt test:
- 1500Vrms at 50-60Hz for 60sec, applied as specified in IEC60850.
What is the foundation of this safety requirement? - insulation: reinforced? - definition of ethernet; SELV or TNV??
If ethernet is used between two SELV circuits, does the requirement of the high electric strength test voltage still apply?
Please help, kind regards
