Calculation of electrical parameters


Power

\[ P = K · U · I · cos φ \]

Voltage

\[ U = \frac{P}{K · I · cos φ} \]

Intensity

\[ I = \frac{P}{K · U · cos φ} \]

- Power (P), W

- Current (I), A

- Voltage (U), V

· Three-phase, Two-phase: between phases

· Single-phase: between phase-neutral

· Direct current: between pole (+) y pole (-)

- K

· Three-phase K = √3

· Other cases K = 1
