Study on Distributed Hardware Platform for Insulated On-line Monitoring System of Capacitive-Type Equipment

SHAN Mao-hua LIU Ji BAI Zhong LU Guo-gang (Nanri Technology Development Limited Company,Nanjing 210003,China)  
In the paper,on-line monitoring system on HV capacitive-type equipment is studied,the indexes of a distributed hardware technology are proposed,and the measure- ment influencing factors such as the current sensor accuracy,sampling rate,AD conversion accuracy,analog signals transmission method,sampling pulse phase synchronism,data com- munication are analyzed.Meanwhile,the design method of distributed hardware is discussed in detail.Based on those aspects,the on-line monitoring equipment is manufactured,the whole synchronizing system of sampling pulse is proposed,and is proved by the experiment. The results indicate that the methods mentioned in this paper are effective and feasible.
