Our DGC based excitation systems are suitable for a wide range of synchronous generators and exciters
driven by virtually any type of prime mover and also for synchronous motors used in pumped storage

The heart of our excitation system is the Digital Generator Controller (DGC).  Designed completely in-
house, our engineers have coupled the finest “off the shelf components” with our custom components to
create a reliable VME based computer platform on which to operate our sophisticated and flexible

The DGC software, operating in the QNX environment, provides all of the features required for precise
control and protection of the synchronous machine under normal and fault conditions.

In most applications, the DGC is backed up by an emergency manual control subsystem which providing
additional level of reliability such that a loss of the DGC computers will not result in a loss of excitation.

Turnkey excitation systems are available with capacity ranges from 10 amps to over 6000 amps.
