What you'll be looking at on Monday morning.
VoltPilot in five acts. Each screen below is the working surface itself: build the model, run the studies, set the protection, inspect the results, hand in the report.
01 · Build
Model your electrical system.
Draw the single-line diagram: place the elements, drag the connections between them, and edit every property in the panel beside the drawing. A transformer carries its kVA, impedance and X/R; a feeder its gauge, length and conduit. The studies read these values — the drawing is the data.

Not starting from a blank sheet? Build the same model in tables instead, or import it from PDF, Excel or a VoltPilot project file.
02 · Analyze
Run engineering studies.
Short circuit solves the whole network at once: three-phase and unbalanced faults at every bus, X/R, first-half-cycle asymmetrical current, and every device checked against its interrupting rating. Load flow, voltage drop with conductor sizing, protection validation, selectivity and incoming load run from the same model — and arc flash to IEEE 1584-2018, computed from the standard's tables you import from your licensed copy.
- Load flow
- Short circuit
- Voltage drop & ampacity
- Protection validation
- Protection × cable coordination
- Selectivity
- Incoming load
- Arc flash
Every result carries its state — up to date, outdated, not run or failed. An outdated number wears a stale seal, and a study that did not converge reports exactly that, not a number.
03 · Protect
Configure and coordinate protective devices.
Set each device the way its trip unit reads: long time (Ir, tr), short time (Isd, tsd), instantaneous (Ii), ground fault — or pick the physical device from the manufacturer catalogs and start from what it actually is. The TCC chart plots the curves as configured; drag a curve and the settings move with it.
- ABB
- Eaton
- Schneider Electric
- Siemens
- Mersen
Under the curves sit the landmarks that make the plot mean something: motor starting and locked-rotor current, transformer inrush and damage curve, conductor thermal limit, available fault current, the device's interrupting limit.
Selectivity between series devices is judged on evidence — manufacturer coordination table first, curve comparison next. Where there is no evidence, the verdict is "unknown", never "selective".
04 · Review
Inspect every result.
Open the calculation memo behind any result: every formula with its values substituted, the standard clause it rests on, and the final number in bold. Ask "why this value?" and the answer names the origin — which engine, which run — the freshness, and the path to the full memo.
A missing input becomes a named absence in the output — never a silent default.
05 · Report
Generate engineering documentation.
The full memorial gathers every study into one document — methodology, incoming load, short circuit, equipment duty, protection settings, coordination, load flow, arc flash — closed by a traceability block that stamps the state of each study. A study you did not run is stamped "not run"; no section goes quietly missing.
- XLSX with panelboard schedules
- DXF of the single-line diagram
- Arc-flash labels (PDF)
