Excitation Systems - Voltage
For rotating (DC rotating generator and brushless)
exciter applications, modern digital Voltage Regulator
(AVR) upgrades replace obsolete voltage regulator equipment.
We provide Digital Voltage Regulators. Digital Voltage Regulator upgrades are
a cost effective solution to improve system response
and generator operation while reducing maintenance
requirements and eliminating obsolescence.
Excitation Systems - Static Exciter
excitation systems require a full Static Exciter upgrade.
These are applied to upgrade
static exciters, or to eliminate DC generator rotating
For these applications, we provide upgrade packages
based on modern digitally controlled Static Excitation
Digitally controlled static excitation systems may
be applied to improve system response and reduce system
losses on DC rotating generator applications. Another
reason for eliminating the DC rotating generator system
is to eliminate troublesome DC commutators and DC field
Upgrading of existing static systems is generally
done to eliminate obsolete or troublesome systems.
For both applications, we provide Digital Static
Excitation Systems which
have been selected to provide safe and reliable operation.
Redundant automatic-manual or automatic-automatic Digital
controllers are often included, especially on larger
systems, to provide additional fault-tolerant operation
in critical applications.
