Hi
While going through the input AC side protection against surges came across this design which uses GDT along with MOV. Wanted clarification on the following points
1. Why GDT is used along with MOV and specifically as per this the midpoint of the MOV connected between the Line and Earth and Neutral and Earth.
2. Is GDT helps in sizing of the MOV to pass the surge.
3. Is it Suggested to replace MOV with GDTs for surge requirements.
Thanks
