Voltage Quality and Power Outage Duration Monitoring

This dataset provides granular, timestamped records of voltage quality events and power outages as detected by AMI meters, including detailed event types, IEEE 1159 classifications, voltage/frequency measurements, durations, and geospatial information. It enables utilities and researchers to analyze grid reliability, identify outage patterns, and improve power quality management.

Behind this dataset

Same schema. As many rows as you need.

These 130 rows came out of a blueprint — 17 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with
  • Event timestamp and meter ID
  • Voltage magnitude in volts (phase A, B, C for 3-phase)
  • Event type per IEEE 1159: sag (<90%), swell (>110%), interruption (<10%)
  • Duration in cycles (1 cycle = 16.67ms at 60Hz) or seconds
  • RMS voltage calculation over 1-cycle or 10-minute windows
  • Frequency deviation from nominal 60Hz (±0.1Hz normal range)
  • Cause code: tree contact, animal, equipment failure, lightning
  • Customer notification for sustained outages (>5 minutes)
