The current transformer is suitable for power system with rated frequency 50HZ or 60HZ and rated voltage 0.5KV or below. It is used for electric energy measurement, current measurement and relay protection.
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
Like any transformer, current transformers have primary, core, and secondary windings, although some transformers (including current transformers) use an air core. In principle, the only difference between a current transformer and a voltage transformer (common type) is that the former is powered by a "constant" current, while the latter is powered by a "constant" voltage, where the "constant" has strict circuit theoretical significance.
