Behind this dataset

Same schema. As many rows as you need.

These 100 rows came out of a blueprint — 21 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

Line ID unique per circuit
From-bus and to-bus connections
Voltage level and number of circuits (single, double)
Line length in miles or kilometers
Conductor type: ACSR, ACAR, ACSS, HTLS
Positive and zero sequence impedance (R, X, B)
Thermal ratings: normal, emergency, winter, summer (MVA or Amps)
Ampacity based on conductor temperature limits
