Calculation method

Calculation method

Modeled neutral current (A)

Phasor sum of supplied same-frequency components; separate harmonic orders must be evaluated separately.

Real phasor sum (A)

Phasor sum of supplied same-frequency components; separate harmonic orders must be evaluated separately.

Imaginary phasor sum (A)

Phasor sum of supplied same-frequency components; separate harmonic orders must be evaluated separately.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • One frequency at a time; phase angles are supplied explicitly. Do not add different harmonic frequencies as same-frequency phasors. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
