Methods
One page per module: what the check does, which inputs it uses, the formulas and assumptions behind it, what it does not check, and the standards it points to.
- Cable Check →
How current, size adequacy and voltage drop are screened.
- Full-Load Current →
Formulas and assumptions for converting power to current.
- Transformer Short-Circuit →
Per-unit estimate of bolted secondary fault current and its limits.
- Power Factor Correction →
Capacitor sizing for a target power factor, and the cautions that come with it.
- kVA Triangle →
The power triangle relating kW, kVAR, kVA and power factor.
- Conduit Fill →
Fill percentage from the dimensions you supply, against the limit for the number of conductors.
- Tray Fill →
Occupancy of a cable tray by area and by width.
- Ground Rod Resistance →
Dwight formula and mutual resistance for rods in a line or ring.
- Resilience Score →
How the relative resilience index is built. Not an availability figure.
- Single Point of Failure →
How single-outage scenarios are generated and evaluated.
- Loading & Headroom →
How percent loading and headroom are aggregated up the system.
- Maintenance Checklist →
How checklist items, instrument classes and document pointers are assembled.
