Power System Analyzer
Three-phase to power factor. This multi-solver chains 2 solvers into a single guided workflow — run each step in order and carry the result forward.

Three-phase power delivers energy on three conductors carrying sinusoids 120° apart, so total power is constant and motors self-start. Line and phase voltages differ by √3, and real power is P = √3·V_line·I·cosφ. The power factor cosφ measures how much current actually does useful work.

Presets
When a transmission line meets a load that does not match its impedance, part of the wave reflects. Incident and reflected waves combine into a standing-wave pattern measured by the VSWR. A perfect match (RL = Z₀, XL = 0) gives VSWR 1 and no reflection — the goal of every antenna and RF design.

Frequently asked questions
- What is the Power System Analyzer multi-solver?
- Power System Analyzer is a guided workflow that chains 2 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.
- Is it free to use?
- Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.
