Application
The T4800 Load Sharer provides
automatic load sharing and system
frequency control for parallel running
generators. The load sharing is
proportional, meaning that the
generators will be loaded equally
compared to their individual capacity.
The load on each generator is compared
with the load on the other generators
and corrected until balance is obtained.
Load sharing is necessary after synchronization
in order to re-establish load
balance and to obtain long term
stability of load and system frequency.
When applied with the B9300 Power
Reference Unit, one or several genera­ tors
can be operated in parallel with the grid
( utility) .
Together with the T4500 Auto Synchronizer,
the T4800 provides the optimal
solution for generator control, both in
marine and land-based applications.
The T4800 is type approved by major
marine classification societies. The T4900
VAr-Load Sharer can also be used as a
supplement. The combination of the
T4800 and the T4900 will provide
complete load sharing of both active
load and reactive load.
