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.

The work at Transformex consisted in creating models of hermetic silicone and resin enclosures for current transducers PP-0.72 made in accordance with the technology of multilayer printed circuits, with three different dimensions resulting from the geometry of current circuits in medium voltage switchgears of Elektrobudowa SA. The works ended with environmental tests at the Institute of Power Engineering in Warsaw.
