SINGLE PHASING
What does single phasing mean: Loads using three-phase power sources are subject to loss of one of the three phases from the power distribution system. This condition is known as "single-phasing." The loss of a single phase on a three-phase line may be due to a downed line or a blown pole top fuse on the utility system. Loss of a single phase may also result from a single-phase overload condition causing one fuse to blow, or an equipment failure within the end-user's facility. About 14% of the motor failures are due to single phasing. Single phasing may occur due to many reason and one that’s reason are rupturing of any one phase in the three phase supply line, open circuit in any the fuses, breaking in the contact of any one phase, due to all such reasons the motor continues to rotate even on that two phases with increased load, approximately around 57% of the load gets increased which are drawn by the other two phases and current increases which trends to damage the mot...
