All components produced are subjected to preliminary and final testing. Our testing room is equipped for carrying out all the standard tests required by CEI and IEC regulations, and for any special requests by the customer, additional testing can be done at approved outside laboratories or by internationally recognized organizations. At this time, instruments be available for carrying out the following tests, simulating all types of environmental conditions:

- no-load testing (computerized)
- short circuit testing (computerized)
- inductance measurement testing (computerized)
- resistance measurement testing
- impulse testing up to 200 kV
- temperature and noise measurement testing
- DC measurement up to 3000A with superimposed ripples
- dielectric rigidity measurement in AC and DC, up to 80 kV (also in water)
- partial discharges measurement
