6.3.9 Analog Input
PATH: ACTUAL VALUES  A2 METERING  ANALOG INPUT
The 745 provides the ability to monitor any external quantity via an auxiliary current input
called the Analog Input. The scaled value of the analog input is shown. In this message, the
name programmed in
S2 SYSTEM SETUP  ANALOG INPUT  ANALOG INPUT NAME is
displayed instead of ANALOG INPUT (the factory default), and the units programmed in

(which is the factory default).
6.3.10 Power
PATH: ACTUAL VALUES  A2 METERING  POWER w W1(3) 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.
