    The starting line current of a 415V,3−phase, delta connected ind...
    The starting line current of a 415V, 3-phase motor depends on the motor's power rating and the starting method used. There are different starting methods such as direct-on-line (DOL) starting, star-delta starting, and auto-transformer starting.

    For DOL starting, the starting line current can be estimated using the formula:

    Starting Line Current = (Motor Power in kW) / (√3 * Motor Efficiency * Motor Power Factor * Line Voltage)

    For example, if the motor power is 100 kW, motor efficiency is 0.9, motor power factor is 0.85, and line voltage is 415V, the starting line current would be:

    Starting Line Current = (100 kW) / (√3 * 0.9 * 0.85 * 415V) = 150.2 A
