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.
