Mr. Jenson,
The MOV solution will take care of the line-line surge, but don't forget
the common mode component of this test

Now you can determine what order filter you need and whether it is

Hello Mr jensen
Just add a MOV between the phases. A 20 mm disc type will survive both
type testing
and real life surges. The smaller ones risc
%.
If it is for mains applications, select transil value according to peak
value of main sinus.

Dear groupe
Dear groupe,
Does anyone have some good idears about designing a simple filter for
surges (the kind of surges that comes from testing according to IEC
61000-4-5)
I was thinking about using an inductor, a capacitor and a MOV. But, what
is the requirements for the inductor ? and will it
