Abstract: Embodiments herein describe a discharge filter, located in a root of a wind turbine blade, which includes one or more cables wound into large scale inductors using an internal or external surface of the root as a mandrel. These cables provide power inputs to an electrical panel for one or more a powered systems that are located in a body of the wind turbine blade. The electrical panel is connected to a lightning protection system that selectively provides a path to ground, and the inductors form a high-impedance barrier that shunts power away from the cables and onto the lightning protection system in the event of a lightning strike or other electrical discharge traveling from the powered systems to the electrical panel.
