A high voltage device includes a circuit board 12 surrounded by an enclosure 11, potting 13 to provide electrical insulation between the circuit board 12 and the enclosure 11, and a layer of material 14, having a different resistivity than a resistivity of the potting 13, dividing the potting into separate and discrete sections. The layer of material 14 can be multiple layers. Each layer 14 can have a voltage applied, and a voltage of any layer 14 closer to the circuit board 12 can have a higher absolute value than any layer 14 farther from the circuit board 12.
