Generator Control

Basic

T4500 SERIES

Auto Synchronizer for Conventional Governors

Description

The T4500 Auto Synchronizer provides automatic

synchronization of a generator to a busbar in a minimum of

time, by controlling the speed via the electric servomotor

on a conventional speed governor, or by controlling an

electronic speed controller via an intermediate motorized

potentiometer. A unique feature of the T4500 is the

possibility of simultaneous synchronization of already

parallel running generators to another busbar section, a

shaft generator or the grid. The T4500 includes outputs for

controlling the Automatic Voltage Regulator (AVR) as well.

When used, T4500 will not only control the speed of the

generator, but also the alternator voltage (Voltage Matching).
