6.3.10 ANALOG INPUT
The 745 provides the ability to monitor any external quantity via an auxiliary current input called the ANALOG
INPUT.
6.3.11 POWER
The 745 calculates and displays real, reactive, and apparent power as well as the power factor for all of the
available windings providing that the voltage sensing is enabled. Power flowing into the power transformer is
designated as source power and power flowing out of the transformer is designated as load power.
The following Actual Values messages are repeated for Windings 1, 2 and 3.
