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

Utilizes a 16-bit high-precision ADC acquisition chip for synchronous voltage and current sampling. Equipped with both hardware and software watchdogs to provide dual protection for the normal operation of modules. Features two-channel hardware interfaces, with an internal relay that can output hardware alarm signals. Includes data storage functionality for peak-to-peak values and RMS values. A customized host computer allows for flexible setting of alarm thresholds, data storage duration, and other parameters. Provides a ±12V power output interface to supply power to the current sensor. Equipped with reverse polarity protection, enhanced EMC designs for improving ability of anti-interference.
