Wind turbine generators face risks such as high-frequency common-mode voltage interference and grounding carbon brush wear, which potentially cause failures compromising mechanical structural stability of the generator.

FS223 shaft voltage and current module, providing real-time monitoring and acquisition of the generator's shaft voltage and current. Module will output a hardware alarm signal and simultaneously records data during the abnormal state, facilitating fault analysis and localization.
