Güç Faktörü Düzeltmesi Akımı Ne Kadar Azaltır?
At the same active power, the current is inversely proportional to the power factor: I₂/I₁ = cosφ₁/cosφ₂. Since losses are proportional to the square of the current, the loss ratio is... (cosφ₁/cosφ₂)²‘dir. Örneğin cosφ 0,75’ten 0,98’e çıkınca akım ≈ %23,5, I²R kayıpları ≈ %41,5 azalır.
Current ratio = cosφ₁/cosφ₂ · Loss ratio = (cosφ₁/cosφ₂)²
Example calculation: cosφ 0,75 → 0,98 → akım oranı 0,765; akım ≈ %23,5, I²R kayıpları ≈ %41,5 azalır. Mevcut 120 A ise yeni akım ≈ 91,8 A.

Notes: At the same active power, I₂/I₁ = cosφ₁/cosφ₂; since line loss is proportional to the square of the current, the loss ratio is (cosφ₁/cosφ₂)². Values are calculated according to your inputs; the same level of relief is provided in cable and transformer capacity.
How is it calculated?

Frequently Asked Questions
How much does power factor correction reduce current?
Akım oranı cosφ₁/cosφ₂ kadardır; örn. 0,75’ten 0,95’e çıkışta akım yaklaşık %21 azalır.
Why does the loss decrease more than the current?
Hat kaybı akımın karesiyle orantılıdır; akım %20 azalırsa kayıp yaklaşık %36 azalır.
What else does compensation provide?
Lower current allows for capacity relief in cables, transformers, and switchgear, resulting in reduced voltage drop and reactive power penalties.
