摘要：
This paper presents metal oxide arresters (MOA) resistive current on-line monitoring and expert diagnosis system. The system combined the harmonic analysis method and the compensation method to measure the MOA resistive current. The on-line monitoring system used MAX11046 for signal AID conversion and TMS320F2812 DSP for data processing. It used EEC 60870-5-103 protocol to upload the data to the expert diagnosis system through the RS-485 bus. Based on the real-time monitoring data, the historical data and the environmental parameters, the expert diagnosis system can analyze and judge the MOA status. The system adopted many anti-jamming measures to make the measurement data stable and accurate. The results show that the resistive current of the 35KV MOA fluctuates based on 20 mu A.
