WebNov 12, 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. WebFeb 2, 2024 · Hence, for both delta and star connections, the apparent power is: S = √3 × V line × I line; Thus, ... If the voltage and current to the motor are 400 V and 8.6 A, respectively, determine the power factor of the delta system. To conduct the correct three-phase power calculation to the problem given above:
