Circuit Breakers and Disconnects
This dataset provides a comprehensive inventory of circuit breakers and disconnects, detailing technical ratings, operational mechanisms, maintenance history, and protection coordination status. It enables utilities and facility managers to track asset condition, schedule maintenance, and ensure regulatory compliance for fault clearing and system protection. Ideal for reliability analysis, risk assessment, and infrastructure planning.

Behind this dataset
Same schema. As many rows as you need.
These 100 rows came out of a blueprint — 18 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
- Breaker ID unique per device
- Voltage class and interrupting rating (MVA or kA)
- Breaker type: air blast, oil, SF6, vacuum
- Operating mechanism: spring, hydraulic, pneumatic
- Three-phase or single-phase
- Normal status: normally open (NO) or normally closed (NC)
- Current status: open, closed, tripped, racked out
- Operations counter for maintenance scheduling
