Data Processing for Dissolved Gas of Transformer

Zhang Weiguo(Qingdao Ocean Shipping Mariners College,Qingdao 266071,Shandong,China)  
Currently,in the DGA on-line monitor system some problem still exist,such as unsteady component function,worse anti-interference function,poor anti-environment factor(such as the variety temperature and humidity) ability,big accumulative error of fault,unsteady measurement data.The article makes use of least squares algorithm to deal with the error.Results show that the optimization data is steady,and reliability is improved..
