Audited Supplier
Special specifications or high-precision products can be made according to user needs. The transformer can be used to measure current, protect current, and is a double-winding current transformer
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
Compact structure: The three-phase current transformer is integrated in a single housing, which saves space compared to single-phase transformers and is suitable for installation in power distribution cabinets and switch cabinets where space is limited.
Easy installation: Because the three-phase transformer is integrated in one unit, the complexity of installation and wiring is reduced, and the
installation efficiency is improved.
Good consistency: Because the three-phase transformer is in the same shell, external factors such as ambient temperature and mechanical stress have the same influence on it, which helps to improve the accuracy and consistency of measurement.
Strong anti-interference ability: the three-phase integrated design can effectively reduce the influence of external electromagnetic interference on the measurement results, improve the stability and reliability of the system.
Easy maintenance: The integrated design reduces the number of components, simplifies maintenance, and only needs to deal with one unit of equipment when it needs to be replaced or overhauled.
Cost effective: Compared to using three single-phase current transformers alone, three-phase integrated current transformers are more cost effective in terms of manufacturing, installation and maintenance.
