Generator Excitation

Gas torque converter

We provide testing and commissioning services for excitation protection systems, reducing commissioning time and achieving early commercial operation. This includes but is not limited to:

  • Generator Under/Overvoltage
  • Active/Reactive Power Reverse
  • Over/Underfrequency
  • Field Overcurrent
  • Field Overvoltage
  • Loss of Field/Sensing Voltage
  • Rotating Diode Protection
  • V/Hz Protection
  • Crowbar Field Overvoltage


Our modern redundant RDEX-5 for brushless applications and the RDEX-10 for static excitation applications up to 3000 Amps are now set to become the new standard in redundant excitation for generators across the spectrum.

Let’s work together!
