Digital Static Excitation System
Transition your old generator static excitation to digital. The Leroy-SomerTM Digital Static Excitation System can be installed on older generators. It combines the proven technologies of a Leroy-SomerTM designed digital AVR like the D550 or D700 and a Leroy-SomerTM Mentor DC drive.
The drive provides a continuous direct excitation current up to 900A, controlled by the digital AVR with the following features:
- Automatic or manual voltage regulation
- Voltage equalization for grid connection
- Cos ϕ, Power Factor or kVAR regulation modes
- Advanced fault detection and data logging
- User-friendly touchscreen interface
