Three phase star connection with different offset

Click For Summary
SUMMARY

The discussion focuses on calculating the voltage required for a balanced star connection with phase angles V1=90°, V2=0°, and V3=-90° to match the phase currents of a standard three-phase voltage source with V1=120V, V2=0V, and V3=-120V. The participant expresses uncertainty about the problem's requirements and suggests that the voltage needed to achieve equivalent phase currents is approximately 180V. Additionally, the discussion raises questions about the system's impedance and the load's power factor angle, indicating a lack of clarity in the problem statement.

Homework Statement


For a balanced star connection i have given angles for V1=90 V2=0 V3=-90 i have to find the voltage required to produce the same phase currents as in standard three phase voltage source e.g V1=120 V2=0 V3 =-120

Homework Equations

The Attempt at a Solution


Im not even sure what t he question is asking me or how to do it my understanding is finding voltage value per 1 degree and just add the difference if voltage is example 230. I am mainly mechanical based so electrical ain't my strong point
 
Physics news on Phys.org
all i have found that voltage rquired to provide same values as 230V is 180V not sure how to mathematically show with correct calculations
 
The problem is not clear.
What is the impedance of the system?
For example, if the phase angle of I1 should be 120°, the load power factor angle should be 30° leading.
Is there any information provided about the load?
