The work at Transformex consisted in designing new constructions of hybrid current-voltage transformers for currents from 25A to 1250A and voltages of 15kV and 20kV, making models and prototypes and finally conducting tests.
The works ended with type tests of transformers. The company obtained a patent for the solution.
