Transformer Setup
The BE1-11g requires information about the transformer windings to provide differential metering and
differential protection. See the
Phase Current Differential (87) Protection chapter for more information.
Transformer setup is accomplished on the Sensing Transformers settings screen (Figure 270) in
BESTCOMSPlus. Setting ranges and defaults are summarized in Table 114.
