Behind this dataset

Same schema. As many rows as you need.

These 400 rows came out of a blueprint — 15 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

GIS bay ID, manufacturer, and rated voltage (72.5kV-550kV typical)
SF6 gas pressure per compartment (psig) and alarm thresholds
Leak detection: infrared camera, sniffer probe (ppm-m sensitivity)
Annual leak rate: <0.5% of gas inventory per year target
Partial discharge monitoring: acoustic sensors, UHF antennas
Moisture content in SF6 gas (ppm, <150ppm typical)
Contact alignment and travel measurements
Environmental regulations: SF6 greenhouse gas emissions reporting (EPA)
