Question

Difference between non linear load and unbalanced load

Answer 1

Answer:

This is so since vector sum of all three phase currents meeting at common neutral point is zero. Unbalanced load makes the lines / phases to carry different current magnitudes, and sum total of these at neutral point is not zero. Load in each phase is different, carrying ts own current.

Answer 2

Answer:

☑ A load is considered non-linear if its impedance changes with the applied voltage. The changing impedance means that the current drawn by the non-linear load will not be sinusoidal even when it is connected to a sinusoidal voltage.
