    The Line Current Calculator allows calculating the current through lines of electrical power given power, voltage, and the type of phase in single or three-phase systems. Line current Line current is the current in any one of the conductors in an electrical system. The calculator is useful in determining line current in both three-phase and single-phase networks since you can use load power, volts, and power factor. Proper calculation of line current guarantees adequate selection of the electrical components as well as effective power delivery.

    Frequently Asked Questions - Line Current Conversion FAQs:

    What is line current?

    A three-phase electrical system experiences line current when each line conductor receives equal currents, which exhibit varying phase positions. The main supply wires transmit power to the load, where the line current is measured. All line currents in a balanced system maintain equal strength, although they have different phase relationships.

    How to calculate line current in a star connection?

    A star (Y) connection relationship establishes an equivalence between phase current flow and line current flow. The knowledge of phase current allows direct calculation of line current because both values are equivalent. Use the formula: IL = P / (√3 × VL × PF), where P = power in watts, VL = line voltage, PF = power factor.

    How to calculate line current in a delta connection?

    The current through the delta system lines measures at a value of √3 times the phase current value. The formula is: IL = √3 × IP. You can also find it using: IL = P / (√3 × VL × PF). The formula provides useful information when powers and voltage value sets are identified.

    What is line ampere?

    The ampere value of the current flowing through each line wire constitutes the line ampere measurement for a 3-phase system. The measurement of line current through a clamp meter or ammeter on any line yields the exact result as line amperes.

    What factors affect line current?

    The line current quantity depends on three factors: the load power (P), the line voltage (VL), and the power factor (PF). When either the load level increases or the voltage decreases, the electrical current rises. Both unbalanced loads and power factors below one lead to increased line current levels, which causes additional losses.
