This type of transformer is made of epoxy resin vacuum casting structure inside and iron shell outside. It is mainly used for electric energy measurement and current and voltage measurement in power system with rated frequency of 50Hz or 60Hz and rated voltage of 10kV or below. This product is characterized by a protective effect on the internal products, can resist pollution, anti-ultraviolet, anti-acid rain, etc., and can be produced with negative control output.
The voltage transformer is made of indoor epoxy resin cast structure with exposed core and stacked with high-quality cold-rolled oriented silicon steel sheets. Primary and secondary coils are installed on the center column.
The current transformer is also made of indoor epoxy resin cast structure, the iron core is closed, and it is made of high-quality cold-rolled oriented silicon steel sheet.
Two voltage transformers (PT) and two current transformers (CT) are assembled in a closed iron box to form a whole.
The performance of products is conformed to IEC61869-1:2007, IEC61869-2:2012 commission requirements
Rated insulation level: 12/42/75kV
Power factor of load: COSΦ=0.8
Rated frequency: 50Hz, 60Hz
Rated secondary current: 5A or 1A
