| Abstract: |
| Among the complex causes of transformer burn out, the overvoltage, overcurrent and manual damage are emphasized and their characteristics are analyzed. It is suggested that: the special tools should be used in its installation, the suitable components should be applied and the connection should be reliable. The maintenance work should be paid great attention after its installation: periodically check the normality and balance of the three phase currents and clear the dirt on the bushing surfaces. The inspection should be carried out according to the technical regulations to find out and remove the hidden troubles. |
