Can someone tell me how much spacing I need around a 1/2 inch round pad and a surrounding
ground plane with 500 VDC differential at 1000 feet altitude and a dusty environment? This is in a high
power application (15KW). I've seen answers ranging from 0.0002 inch per volt for non-coated
boards in an old MIL-STD-275, to 0.5 inch in a VDE handbook. I need a good practical
answer and would greatly appreciate a response.
