China, Sichuan: China is building an ultra-high voltage substation at the highest altitude in the country so far.
The construction of a 1,000 kV substation in Ganzi Tibetan Autonomous Prefecture of...
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...
Foil coil is mainly used for small and medium-sized transformers with capacity less than 2000KVA. The advantages of foil coil are: good mechanical strength, not easy to deformation, can withstand s...
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 ...

Q1) what are instrument transformer?
If we want to measure extremely high values of current and voltage than there are two ways of measuring it. One is to use high capacity instruments which would ...
