Line supply connection conditions for Booksize Line Modules

1.3.2.1

Transformer design for connecting Booksize Line Modules to the line

supply

A transformer should be used for connecting Booksize Line Modules to the line

supply. The following diagram shows connecting a Booksize Active Line Module to

an isolation transformer as example:

Fig. 1-2

Two important constraints must be taken into consideration when selecting the

correct transformer.

1. The relative short-circuit power at the Line Module connection point

2. The minimum rated transformer power taking into consideration the

supplementary transformer losses as a result of line-side harmonic currents
