Phase voltages from line voltages calculations

    How can we calculate phase voltages from the line voltages when the 3-phase system is unbalanced?

    If you know what the imbalance is, you can use the voltage-phase vectors to figure that out. Of course, if the imbalance is due to other loads out of balance, adding a new load will shift the imbalance around.
