Viewing Actual Values

GE Multilin
This window allows the desired addresses to be written to User Map locations.
The User Map values that correspond to these addresses are then displayed.
You can view real-time relay data such as input/output status and measured
parameters. From the main window menu bar, selecting Actual Values opens a
window with tabs, each tab containing data in accordance to the following list:
1. System Status:
– The status of the logic inputs and virtual inputs/outputs
– Targets.
– The status of the output relays.
– Any self-test errors.
2. Metering Data:
– Instantaneous current measurements including phase, neutral, and ground
currents for each winding, along with differential, restraint, positive-
sequence, negative-sequence,
currents.
– Harmonic metering up to the 21st harmonic, total harmonic distortion
(THD), as well as harmonic derating factor.
– Phase-to-neutral voltage metering, volts-per-hertz, and system frequency.
– Tap changer position.
– Current demand for each winding including peak values.
– Real, reactive, and apparent power for each winding, along with the power
factor.
