Question

• Mainly the unbalanced load can be three phase system or load in which the voltage or current show more significant unbalance because of below following reasons.
• If the three phase load is motor then the mechnical stresses due to less torque than normal output.
• Higher current in the load.
• Because of higher unbalaance current in the load the unbalance voltage in the system increased.
• Torque pulsation increases
• Increase of vibration
• increase losses
