ABSTRACT:
A grading layer for a slot armor in an electric machine employs a layer of semi-conducting particles of silicon carbide bonded to the face of insulation of the slot armor. A layer of a tough high temperature paper such as an aramid paper separates the silicon carbide from the windings. The voltage gradient at the radially outerward extremity of the windings is capacitively coupled through the aramid paper to the silicon carbide layer wherein span-wise conduction decreases the peak voltage gradient to reduce the likelihood of the formation of corona and flashover.
