A New On-line Detecting System of MOA and Its Simulation

Wang Xue et al  
A new system for on-line detection of MOA is presented. By detecting the leakage current of each phase to acquire the three-phase grounding current, based on the radical resistive current, zero order current and third order harmonic current, the operating condition of MOA can be diagnosed synthetically. The DSP device is employed as the data processing unit, for realizing the on-site configuration of operating parameters, on-site display of diagnostic results and background management of on-line data. The new system can be expected to improve the fault diagnosis sensitivity of MOA greatly.
