    Frequently Asked Questions - Line to phase-current Conversion FAQs:

    How to calculate phase current from line current?

    The determination of phase current through line current requires a division by the square root of 3 (1.732) value. Under balanced load conditions in a star (wye) connection phase current maintains an equal value to the line current. A delta-connected system calculates phase current by dividing line current by the value of 1.73.

    How to calculate per-phase current?

    System current distribution takes place through per-phase current, which derives from dividing the total current by the phase count. All three-phase systems maintain equal currents in each of their phases. The method to determine per-phase current involves dividing the line current by √3 for delta connections or by a simple line current measurement in star connections.

    How to calculate load phase current?

    The current calculation for the load phase relies on both the system-connected total load and the phase count. The load phase current measurement for balanced three-phase loads requires dividing total power or load by voltage, then taking the one-third power (in delta systems) or just dividing by load voltage (in star systems).

    What is the relationship between line current and phase current?

    The relationship between line current and phase current depends on the system configuration between a star and a delta. The connection of stars determines that the line current remains equal to the phase current. The line current in a delta connection equals √3 times the phase current value.

    How does phase current relate to system voltage?

    A three-phase system needs phase voltage, together with the connected load type, to calculate current measurements. The calculation for phase current uses the ratio P / (V × √3) when the load is balanced and incorporates total power P as well as phase voltage V. The delta configuration uses line voltage instead of phase voltage in a delta.
