Abstract
A vacuum pressure impregnation process includes placing a room temperature coil/winding into a pressure vessel with a camera aimed at the coil/winding for inspection, and sealing the pressure vessel to draw a first vacuum level, maintained for a first duration. The coil/winding is flooded with resin and remotely monitored. A second vacuum level is maintained for a second duration while remotely monitoring. A first positive pressure level is applied for a third duration while remotely monitoring, before releasing and drawing a third vacuum level, maintained for a fourth duration while remotely monitoring. A second positive pressure level is applied for a fifth duration while remotely monitoring, before releasing pressure and removing the coil/winding from the pressure vessel.
