Spare Parts for GE ALTERREX Excitation Systems
ALTERREX excitation systems were supplied for large steam turbine generators between 1965 and 1992. A shaft-driven alternator-exciter with a stationary armature and rotating field provides the excitation power. A set of stationary diode bridges rectifies the alternator output which is then applied to the main generator field.
The OEM has declared the obsolescence of the ALTERREX excitation system. GTC carries a significant inventory of spares and can perform repairs to avoid a costly excitation control system upgrade.
