Insulation system and method for a transformer

摘要

A transformer (10) including a magnetic core (14) is provided. The magnetic core (14) includes multiple laminate stacks having at least one opening. The transformer (10) also includes a winding (30) comprising a conductive material around the magnetic core (14) through the at least one opening (20) and surrounded by an insulating layer (54) having a dielectric constant that varies as a function of voltage.
