line to phase current calculator
Convert three-phase line current to phase current and vice versa in star (Y) and delta (Δ) systems for accurate AC circuit analysis.
three-phase current conversion
The extent of line to phase current correlation assumes a relationship that varies in any of the types of connections in three phases. In the case of star connections, there is equality between the line current and phase current. In the case of a delta connection, the phase current is 3 times the line current. This calculator makes converting between line and phase current easy to do correctly when going through the analysis of AC.
Formula & Table Summary:
Star (Y) Connection: I_line = I_phase
Delta (Δ) Connection: I_line = √3 × I_phase
Conversion (Delta): I_phase = I_line / √3

The Line to Phase Current Calculator assists in changing between line and phase currents in three-phase electrical circuits, which may have either a star (Y) or delta ( D ) electrical system. The line current in a star (Y) connection is the same as the phase current, and with a delta (Delta) connection, the line current is 31/2 times the phase current. Transformer sizing, Motor load analysis, and protection device selection depend on correct conversion. The tool enables engineers, electricians, and students to easily find phase currents based on known line currents or vice versa to aid with balanced and unbalanced three-phase systems. Proper design, load distribution, and safety accuracy on three-phase AC circuits must be achieved through the utilization of such calculations.
