Estimate maximum demand and diversity, correct power factor, check harmonics against IEEE 519, assess voltage unbalance and motor derating, balance panels, convert kW, kVA and amps, and estimate electricity bills and NEC 220 residential loads.
IEC 60831 capacitor bank sizing with current/kVA reduction. Harmonic resonance, detuning reactor sizing and energy-savings analysis are advanced features.
IEEE 519-2014 Table 1 (voltage) & Table 2 (current, TDD-referenced) distortion limit checks. Full per-order breakdown table and K-factor estimate are advanced features.
Load-category demand-factor method with design current and breaker sizing. Multi-board site aggregation & transformer sizing is an advanced feature.
NEMA-style % voltage unbalance and motor derating factor from the NEMA MG1 / ANSI C84.1 curve.
Per-phase load balance and neutral current from the standard 3-phase phasor formula.
Single-phase and three-phase power-triangle and current conversions from a load profile (voltage, power factor, and any one known quantity).
Estimates a monthly electricity bill from itemized time-of-use energy, peak demand charge, fixed charge and an optional power-factor penalty.
Diversity factor and coincident maximum demand for a group of loads on a shared feeder, transformer or panel, with compute and solve-for-unknown modes.
Single-family dwelling service load via NEC Art. 220 Standard Method or 220.82 Optional Method, with recommended minimum service size.
Why fixing power factor can introduce a new harmonic problem, how demand-factor sizing accounts for diversity, and why utility tariffs are the one part of this category with no universal standard behind them.
