Micadur: Compact insulation system for medium-sized turbo generators
Abstract
A high voltage, Class F, vacuum pressure impregnated insulation system for wound stator cores of the medium size turbogenerators is described. With this total impregnation technique the insulation process has been revolutionized. The excellent characteristics of this synthetic resin insulation system have made it possible to redesign the end winding support system for decisive improvement in reliability. This has been confirmed by operating experience in recent years. Test procedures were modified to suit the new insulation process and new repair procedures have been developed.
