The T4300 Load Sharer provides automatic load sharing for parallel running generators. The load sharing is proportional, meaning that the generators will be loaded equally compared to their individual capacity. The T4300 works in connection with most electronic speed controllers.
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 the load. When applied with the B9300 Power Reference Unit, one or several generators can be operated in parallel with the grid (utility). Together with the T4000 Auto Synchronizer, the T4300 provides a good solution for generator control in many land-based applications.
The T4900 VAr-Load Sharer can also be used as a supplement. The combination of the T4300 and the T4900 will provide complete load sharing of both active load and reactive load. An interesting alternative to the T4300 is the T4400 Load Sharer. In addition to the features of the T4300 the T4400 Load Sharer includes a built-in frequency control and an integration function.
These two features provide a very high overall stability and compensate for any drift within the speed controller. A soft load / unload function is also provided in the T4400.
