The formula for phase current in a delta winding isn't directly given, but can be derived from the relationship between line current and phase voltage in three-phase delta systems, considering Ohm's Law and circuit laws for more detailed calculations.
The formula for the phase current in a delta winding is not provided explicitly in the provided reference material. However, deriving it generally involves understanding the relationship between phase voltage and phase current in a delta (Δ) configuration. For a delta-connected system, the phase current (Iφ) is equal to the line current (IL).
The phase voltage (Vφ), on the other hand, is the voltage across each winding, and it is related to the line voltage (VL) by Vφ = VL / √3. Therefore, if the power factor and total power are known, the phase current can be calculated using the power formulas for three-phase systems. When impedance and phase angle are considered, more complex calculations involving Ohm's Law and Kirchhoff's circuit laws are required.
