ANALISIS PENINGKATAN FAKTOR KERJA MOTOR INDUKSI 3 PHASA

Abstract

Following to the rapid indrustry, where many major indrustries using electric motors and other electrical
equipment that is inductive, so that the reactive power consumption increase. For indrustrial low power factor
cannot be avoided because each motors has variable load. Induction motors with a full load can provide high
power factor, but when the motor is low, its power factor will decrease. Its condition can be overcome by using
capacitors. Capacitors are mounted paralell to the motor can be used to improve the power factor. The value of
the capacitors depends on the reactive power generated by the motor. Component reactive power inductive
should be reduced and the reduction can be done by adding capacitor. The reduction process can occur because
the load is inductive and capasitive its opposite direction due to its reactive power into a small and show that at
22 % load power factor improvment occurs 0.5151 into 0.5174.
