What is mean by balanced and unbalanced load?

There is a lot of confusion amongst consumers that an Unbalanced Load

Stabilizer is generally superior to a Balanced Load Stabilizer. To clarify

this myth certain fundamental principles connected with Transformers

are given below:

1. Definition of Balanced and Unbalanced loads:

a. A Three phase Loads on a 3 phase supply system is a Balanced

load because it draws equal current from each phase. Three phase

Motors, Converters; Rectifiers using 3 phase input supply are

common examples of Balanced loads.

b. A single phase / 2 phase loads on a three phase system is called

Unbalanced load. Normally Unbalanced loads have to use a

neutral wire in the system. The 2 phase loads may not require a

neutral.
