METHOD AND APPARATUS FOR DEHUMIDIFICATION OF GENERATOR WINDING INSULATION

摘要

The present disclosure relates to electrical generators, more specifically to an apparatus and method for dehumidifying the windings and insulation system of a generator. The application of low-voltage, low-frequency, high-AC-current provides precise control of the rise of temperature in the winding. The controlled temperature increase occurs uniformly over the complete length of the winding, providing uniform dehumidification of the insulation system such that connection to the inverter and power production occurs without risk of damage to the insulation system.
