Automatic Phase & Neutral Balancing System is a three phase system which is installed near the load at low voltage supply line between phases and neutral i.e. parallel to the impedance. APNBS due to its magnetic symmetry tries to establish neutral point symmetrical with respect to phase voltages. The effect in turn reduces the difference between unequal voltages in three phases and reduces the neutral current.
