The function of using three-phase factor controller have below four advantages.Electricity charges can be saved by power factor discount. Effective use of facility capacity can be realized by power loss reduction.Labor saving by work reduction of power factor adjustment.Equipment life can be extended by stabilizing circuit voltage.The modified power-factor controller, developed at the Marshall Space Flight Center, employs a phase detector for each of the three phase windings of a delta-connected induction motor. The phase-difference sum is the basis for control.Instabilities of earlier systems are overcome with improved feedback control incorporating a 20Hz bandwidth signal.
