A New Concept of Combined Transformers

The basic characteristics of a new concept of combined transformers consisting of an inverse current transformer and a voltage transformer with open core, are described. The results of the research and testing of impulse and AC voltage distribution, accurency class, influence of the current transformer on the voltage transformer and vice versa are given. Thanks to its technology and simplicity, the new concept allows the commercional manufacture of combined transformers for the highest equipment voltages up to 420 kV inclusive.
