Rotating Diodes

In collaboration with the Université d’Artois (France) and Hydro-Québec, our engineering team has designed an exciter modernization solution for use in hydro-electrical power stations. The solution includes design work and plans and all modifications to the exciter, while requiring no modifications in the power station.

MODERNIZATION BENEFITS:

  • No maintenance required
  • Useful life of 40 years with no maintenance
  • No creation of dust by brushes, which extends the useful life of the main alternator
  • No change in the load on the main shaft
  • Time constants lower than or equal to operating a direct current exciter
  • Excitation current lower than or equal to operating a direct current exciter
  • Elimination of all sliding contacts
  • Elimination of commutator
  • Elimination of field circuit breaker
  • Elimination of interpoles
  • Minimal unit installation time
  • Spare parts inventory reduced to minimum
