Nettet12. nov. 2024 · TL;DR (Too Long; Didn't Read) Perform a three-phase power calculation using the formula: P = √3 × pf × I × V . Where pf is the power factor, I is the current, V is the voltage and P is the power. Single-Phase vs. Three-Phase Power. Single- and three-phase power are both terms describing alternating current (AC) electricity.
