Abstract

A wind turbine rotor blade is provided. The wind turbine blade has a lightning receptor, a first electric line, and a potential equalization arrangement having a first electrode, which is connected to the lightning receptor, and a second electrode, which is connected to the first electric line, a spark gap being formed between the two electrodes, mutually facing sides of the two electrodes forming an air flow channel, which is arranged such that the ambient air that is incident when the wind turbine rotor blade is in operation flows through it.
