3.2 Description of the Excitation System
UNITROL 1020 is an automatic voltage regulator of the latest design for
synchronous generators and synchronous motors. The unit contains the
most advanced microprocessor technology together with IGBT
semiconductor technology (Insulated Gate Bipolar Transistor).
The mechanical construction is extremely compact and robust.
UNITROL 1020 operations are effected through a practical and simple-
to-operate panel on the unit. In addition, user-friendly software facilitates
commissioning and allows optimization of operation.
The UNITROL 1020 unit can be connected to a 40 A Power Module
called UNITROL 1000-PM40. For further information refer to the
separate User Manual.
