What is openXDA?
• A back-office automated service to
automatically process and analyze event
and trending data from transmission and
distribution metering – DFRs and PQ
metering

openXDA – PQ / DFR Dualism
• PQ Data – Largely distribution focused
 Single line monitoring
 Self-describing configuration in PQDIF
 Data may be collected by MDM systems
 Event and trending data
• DFR Data – Largely transmission focused
 Multiple lines monitored
 Meter configuration information (channel
mapping) required
 Only event data, typically as COMTRADE files

What is the open PQ Dashboard?
• The presentation layer PQ data housed in
openXDA.
The openPQ Dashboard has been primarily funded by
EPRI with extensions and contributions provided by others.
17
A System Wide Dashboard
• Provides a full enterprise view
• Easy-to-understand navigation for quick drill-down to
detailed PQ data
• Enables insights not possible with manual display tools
• Identifies actionable trends
• Measures efficiencies/inefficiencies
• Filtering allows insights and decisions on specific
populations
• Enables quickly identification data outliers
