At the moment of the epidemic, our steps are not stopped. In the severe epidemic situation that has lasted for nearly half a year in the East China Plain, especially in the case of the suspension o...
The thermal stability of the insulation material is the main factor affecting the life and overload capacity of the oil-immersed transformer. By explaining the preparation process, physical and che...
I.Cause of Partial Discharge
The transformer insulator, metal body and so on are often with some sharp angle and burr, so the electric charges under the action of electric field intensity will conc...
China, Beijing: China started with the construction of an UHV DC transmission line.
China started with the construction of an ultra-high voltage (UHV) direct current (DC) transmission line that wi...
effect of temperature on high pressure test
The change of temperature will fully affect the insulation resistance, so when the external temperature continues to rise, the movement of molecules and ...
Distribution transformers normally have ratings less than 200 kVA,[2] although some national standards can allow for units up to 5000 kVA to be described as distribution transformers. Since distrib...
