Reduction of energization transients in a three phase Y-connected load
having legs A, B and C associated with corresponding phases of a three-phase AC
power system is achieved by energizing respective legs of the load in an order
determined by a energization sequence dependent upon a type of the load. The energization
sequence defines first, second and third legs of the legs A, B and C to be energized.
A conduction path for current to flow between a neutral point of the Y-connected
load to ground through a transient-limiting impedance while the first, second and
third legs are being energized is employed. The transient limiting impedance has
an impedance value selected such that after the first leg is energized, an energization
transient produced on energizing the second leg and an energization transient produced
on energizing the third leg are both approximately minimized.
