Tests and diagnosis
We carry out predictive and preventive tests, both in the plant and in the workshop, on all types of rotating machinery, with state-of-the-art instrumentation and highly qualified technical staff with extensive experience in the sector.
With the confidence of a highly specialised and professional service, our activity is structured around our experience and dedication that covers a multitude of sectors, including marine and cogeneration.
We are experts in technical assistance
- Visual inspection: core, coils, rotor winding, excitation.
- Evaluation of loose wedges.
- Stator insulation tests: insulation resistance, IP, capacity/delta tg and dielectric losses, partial discharges, ohmic resistance, high frequency shock wave.
- Insulation tests on rotors: detection of short circuits between turns and to ground.
- EDA tests (Insulation evaluation and diagnosis), using the charge and discharge current method.
- Measurement of dielectric strength in DC and AC.
- Capture of thermographic images.
- Measurement and diagnosis of the vibrational state of machinery using spectral analysis, modal analysis and impact test.
- Checking for short circuits between elementary turns using a high frequency shock wave test.
- Vacuum and load test both in the plant and in the workshop.
- Drilling test of straight parts and coil heads.
- Temperature stabilization measurement in rotating machine bearings.
