| Abstract: | Traction transformer is one of important components of the traction power supply system.Since inner fault may be found easily by on-line monitoring for traction transformer,it is very important for safety of high-speed railway.DGA(dissolved gas-in-oil analysis) is an effective technique to detect the running state of transformers.In this paper,on-line monitoring system for traction transformer was designed by using DSP technology. |
