• 220 V
,6 A COS φ =0,6 olan tek fazlı motorun güç katsayısını 1 yapmak için bağlanacak kondansatörün kapasitesini bulalım.

• Cos φ
y=0,6 ise φ y=53,13 ° • cos φ =1 ise φ=0 ° • Ic=Iy.cos φy(tan φy-tan φ) • Ic=6*0,6(tan53,13°-tan0°) • Ic=3,6(1,33-0) • Ic=4,8 A • C=Ic/2wu =4,8/6,28*50*220=6,95µF

Bir tesisin aktif
gücü 50 kW, cosφ=0,65 dan 0,90’a yükseltilmek isteniyor. Bunun için gerekli olan kondansatörü tayin edelim.

P= 50.000 W Cosφ1=0,65
φ1=49,5 Cosφ2=0,90 φ2=25 Qc=P. (tanφ1- tanφ2) Qc=50. (1.17-0,46) Qc =35,5 kVAR

Tesisimizin aktif gücü
8 kW, cosφ=0,83’den 0,95’e yükseltilmek isteniyor. Bunun için gerekli kondansatörün kapasitesini hesaplayalım.
