HMI Configurations
Customized Device Overviews can be saved as HMI Configurations. To save the
current configuration, select Tools > HMI > Save Configuration to save the
configuration under the current name, or Tools > HMI > Save Configuration As
to specify a configuration name.
HMI configurations are identified by relay type and a configuration name. To use
an existing configuration, select Tools > HMI > Select Configuration. To view
available configurations, select Tools > HMI > Manage Configurations. To
make an existing configuration the default configuration for a given relay type,
select the configuration in the Manage Configurations window, select Edit, and
select the Default check box.
Analyze Events
QuickSet has integrated analysis tools that help you retrieve information about
protection system operations quickly and easily. Use the protection system event
information that relays store to evaluate the performance of a protection system.
Event Waveforms
Relays record power system events for all trip situations and for other operating
conditions programmed with SEL
OGIC control equations.
The relays provide two types of event data captures:
➤ Event report oscillography that uses filtered sample-per-cycle data
➤ Unfiltered (raw) data
Use QuickSet to view event report oscillograms, phasor diagrams, harmonic
analysis, and settings.
Read History
You can retrieve event files stored in the relay and transfer these files to a com-
puter. To download event files from the relay, open the QuickSet To ols > Event s
menu on the QuickSet toolbar and click Get Event Files. The Event History
dialog box will appear (similar to Figure 2.20).
