Analog Input; Power - GE 745 TRANSFORMER MANAGEMENT RELAY Instruction Manual

6 ACTUAL VALUES
The 745 provides the ability to monitor any external quantity via an auxiliary current input called the ANALOG
INPUT.
S ANALOG INPUT

ANALOG INPUT:

0 µA
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.

This message displays the scaled value of the analog input, as defined by
the setpoints noted above. 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
S2 SYSTEM SETUP/ANALOG INPUT/ANALOG INPUT UNITS are displayed instead
of µA (which is the factory default).
