Integration & Analytics — Disturbance Event Historian

COMTRADE Adapter

Automatically retrieves IEEE C37.111 COMTRADE and PQDIF disturbance files from IEDs and disturbance recorders and historizes them in AVEVA PI Server™ — giving protection engineers one unified view of every fault event, correlated with process data instead of buried in offline folders.

COMTRADE Adapter: lightning over a city illustrating grid fault events

Automated 
​File Retrieval

Pulls IEEE C37.111 COMTRADE and PQDIF disturbance files from IEDs and disturbance recorders via FTP or IEC 61850, with no manual file transfer.

Unified Historian View

Historizes every extracted data channel as a PI Tag and links each event to its power system asset via PI Asset Framework, correlating fault data with process data in one place.

NERC PRC-002-2 Compliant Archiving

Stores the complete original disturbance file in a PI Event Frame™ with a full audit trail, supporting five-year retention requirements.

What COMTRADE Adapter Delivers

Fault event data captured by IEDs and disturbance recorders typically stays on the device — retrieved manually, stored inconsistently, and disconnected from engineering analysis tools. COMTRADE Adapter closes that gap, bringing disturbance data directly into your PI historian as part of normal operations.

  • Automatic retrieval and historization of IEEE C37.111 COMTRADE and PQDIF disturbance files via FTP or IEC 61850, with no manual file transfer
  • Automatic PI Tag creation for each extracted data channel, with no manual tag pre-configuration required
  • Complete original disturbance file stored in a PI Event Frame™ for central archiving and forensic analysis
  • Direct linkage of each disturbance event to its power system asset via PI Asset Framework (PI AF), correlating fault data with all other process data in the historian
  • PI Notifications™ triggered on file receipt and processing, enabling fast alert and response to power system faults
  • Bidirectional COMTRADE export — any PI Tag data can be exported to a COMTRADE file for protection engineering tools and relay playback
